Do I need another caching plugin other than Pegasaas Accelerator WP?

No, we recommend you do not use other optimization plugins at the same time as Pegasaas Accelerator WP, as doing so may cause a conflict.

Can I use other web performance optimization plugins while using Pegasaas Accelerator WP?

We do not recommend you operate other optimization plugins as doing so could cause a conflict in operations, as well as cause your WordPress website to run unnecessarily slow due to a duplication of functionality.

Search Filter Bug Fix (December 31, 2020)
* This patch includes a fix for the Pegasaas dashboard search filter that was brokein in 3.5.0, as well as a number of smaller code tweaks.

3.5.0

Improved Installer, Prioritized Page Optimization, Performance Improvements (December 30, 2020)
This minor release improves a number of UI and UX aspects of the plugin.

Improved Installer
* The installer now has a separate step for the compatibility checker, which is now more comprehensive.
* In many cases, the compatibility step can now also be skipped.
* The installer will also jump immediately to the dashboard upon fetching/validating an API key, cutting the “initialization” time down considerably.

Prioritized Page Optimization (Beta)
* Premium API plans will now include the ability to mark pages to be prioritized above the rest in a site, so that those pages are optimized ahead of the rest of the site.

Performance Improvements
* Added a large data structure to the cached data storage system. This speeds up the /wp-admin/ dashboard load by as much as 1 second/1000 pages. This may only be noticable for sites with over 2500 pages.
* Changed some API communication methods to be non-blocking
* Made re-optimization requests less intense on the website’s web server by maximizing the number of requests in the queue.

Automatic Web Performance Rescans
* Re-activated this feature from v3.1
* Re-scans now happen automatically on re-optimization (provided not a significant number of web performance scans haven’t been submitted in the last 24 hours)

3.4.0

API Submit Method (December 11, 2020)
This minor release improves the mechanism that submits the optimization request to the Pegasaas API. 

Until 2020 (prior to v3.0) the default behaviour used non-blocking calls from the plugin to the API.  In 2020, this behaviour was switched to a blocking call in order to improve reliability. 

In version 3.4.0, the submission system will be a hybrid mechanism: blocking unless the plugin experiences a communication fault when submitting an optimization request.  If a timeout or error is encountered, the plugin will switch to a non-blocking submission method which includes a background check (run every 10 minutes) to ensure that any pending requests that were submitted via the non-blocking mechanism were indeed received by the plugin.

This new setting (found in Settings -> Miscellaneous -> API Submit Method) is configurable — you may choose between the new “Auto (Hybrid)”, “Blocking”, or “Non-Blocking” methods.  You can also now set the timeout duration for blocking api requests, as well as the the time period that the system will enter into a “non-blocking” mode, if you’re using the new default method.

3.3.12

Redirection Bug Fix (November 17, 2020)

* Resolved issue in some Elementor interfaces where the Elementor post/page editor would not fully load

3.3.9

WPX Cloud and jQuery Updater Compatibility (October 16, 2020)
* Adjusted the Cache-Control parameters for WPX Cloud so that the wp-admin and wp-login.php endpoints are not cached
* Added jQuery Updater script signatures for better reliability in jquery script execusion when deferring javascript

3.3.8

Elementor Compatibility / Small Bug Fixes (October 6, 2020)
* Added new feature which provides a much needed boost for sites powered by Elementor. This feature is automatically enabled, but can be disabled in the Settings->Compatibility section.
* Resolved issue where some sites were having “unoptimized” pages automatically optimized.
* Set the upper limit on the number of web performance scans, to return as a part of the score, to 1000 (as greater than 1000 can cause memory issues).

3.3.7

Compatibility Improvements (September 18, 2020)
* Resolved issue where when trailing slashes were disabled in the site, the .htaccess instructions plugin would not pull from cache properly.
* Added better support for WPML and WooCommerce Multilingual plugin
* Corrected issue with persistant long-loading background AJAX request.

3.3.6

Compatibility Improvements (September 11, 2020)
* Slow Server Compatibility: increased compatibility test timeout to allow for slower web servers

* WooCommerce: Improved performance when upating orders
* WPML: Now supports multi-domains configuration
* Caldera Forms: Better compatbility for Caldera Forms API

3.3.2

Additional Compatibility for AMP (July 9, 2020)
* Prior to this update, some of the advanced features of AMP were not being applied to the page.

3.3.1

Interface Performance Improvements (July 9, 2020)
* Adjusted compatibility with the “redirection” plugin which improved interface load time.
* Added remote testing capability to determine server reponse time of the server.
* Adjusted description for compatibility check failure when a blank response is returned from the test submission. Description now states that the server is too slow.

3.3.0

Auto Pilot Modes (June 26, 2020)
This minor release adds the new “Auto Pilot” setting to the plugin.  Upon installation, the user now has the option of chosing from “basic”, “supersonic”, “hypersonic” or “beast mode” auto pilot modes.  Should the user wish, after initialization, the user can put the system into “manual configuration” mode.

The new “Beast Mode” setting gets the fastest speeds available, but some of the features (HTML Lazy Loading, Deferring Unused Javascript) are considered highly experimental and may not work with every website, so this mode should be used with caution.

There have been a number of other updates to the plugin since the last release, including support for the “WebP Express”, “BunnyCDN”, and “WP Daddy Builder” plugins.

3.2.2

Added ability to handle very large web pages. (May 25, 2020)

3.2.1

Resolved bug that caused Elementor to not be able to edit pages. (May 15, 2020)

3.2.0

Upgraded Web Performance Data Fetch Method (May 14, 2020)
* This minor update added support for a “notify and fetch” method of submitting web performance data to the plugin.  In previous versions, the API would submit the web performance data back to the plugin directly once a scan was complete. 
* In this new version, the plugin is notified that the results are ready and then the plugin immediately fetches the data.  The reason that we moved to a “notification and fetc”h (vs “direct push”) method was that some web servers were blocking the web performance data submissions, and thus the installation would never complete.
* While this will not resolve all hung installations, this should account for a large number of failed attempts to get the plugin initial scans completed.

3.1.14

Compatibility for Third Party Vendor Scripts, Plugin, and Hosting (May 7, 2020)
* Added support for third-party vendor scripts (Subscribers, Ngageics)
* Added support for Optimole Image CDN

* Removed calls to API to clear API remote cache on Combined CSS and Deferred JS as those resources now exist with timestamped filenames

3.0.0

Version 3.0 has been four months in the making, and as such the list of changes and improvements are vast.   Here are a summary of the updates:

• NEW *

• Staging Mode – for live production websites that want to test the plugin and how it performs prior to going live

• Global Basic Coverage – basic converage of foundation web performance features for those pages that are not explicitly declared with premium acceleration
• Generic CDN for Whitelabel Agency plans – automatically uses a generic domain name to obfuscate the fact that the CDN is run by Pegasaas
• Lazy Loading for 3rd Party Vendor Scripts – everything from Google Tag Manager to Google Maps, LiveChat to Tawk, some 25+ vendor scripts can now be briefly lazy loaded in order to shorten the initial load time of your web pages
• Multi-Server Support – if you run your website via multiple load-balanced AWS websites, the plugin will communicate with our API which will in turn communicate with each web server that you run, to make sure that the optimizations are deployed to each server, and that cache is consistent between the installations
• Clear CDN Cache Elements – if you’re using the CDN, you can now clear individual files from the global CDN
• Projected Bounce Rate Reduction – we now estimate your bounce rate reduction based upon market research that for every second saved, bounce rate tends to decline by 7%
• Projected Conversion Rate Improvement – we now estimate your conversion rate improvement based upon market research that for every second saved, conversion rates tends to improve by 12%
• CDN Cache Busting – you can now enable this feature which will append a timestamp to the end of any CSS or JS file, if you are one to make regular updates to those types of files in your site
• Support for new inline-script-block deferral  – this replaces the previous method of externally compiled javascript files
• Support for Lazy Loading of dependent script blocks
• Caching Enabled for AMP pages
• Defer Unused CSS – you can now specify which “action” you want to trigger the loading of the deferred CSS files (click / scroll / click or scroll)
• Lazy Loading Iframe Exclusions – you can now specify URLs of iframes to exclude from lazy loading

• Retain Image Metadata – You can now opt to retain the image exif metadata in your pages when optimizing them through the CDN

• UPDATED *

• Pickup Stale Requests – the plugin will now check the API for requests that may have not been received

• Interface – major overhaul of the UI which includes faster load time of pages in the dashboard
• Mega Menu – global pagespeed scores are no longer displayed as calculation of the metrics was causing the dashboard to load slowly for those sites with 500+ pages
• Cache Clearing – this is now done as a background process so as not to incur timeouts on the dashboard.
• Settings Page – major overhaul of the UI and functionality which now uses background AJAX calls to speed up the saving of features
• Nginx Support for domain aliases – the plugin will now first check that the domain name that is being used to request the page is the primary domain name in the WordPress settings before serving the cache.  If it finds that the domain names do not match, the plugin will allow WordPress to do a redirect to the primary domain.

2.8.19

Compatibility (Yith Woocommerce Wishlist, CSS)
* This update adds compatibility for the Yith Wishlist plugin by detecting if Yith is in installed and if the current session’s user has a wishlist.  If the user has a wishlist with at least one itme, then cache is bypassed and the page is dynamically generated.
* A minor change to the CSS for the post-pages panel was made to accomodate those plugins that use a “search” function (search field had white text on white background).

2.8.18

Output buffer handling error fixed (introduced in 2.8.16)

2.8.17

Output buffer handling error patched (introduced in 2.8.16)

2.8.16

* Added support for the Easy Digital Downloads ecommerce plugin — plugin will now bypass cache if it detects there are items in the EDD cart.

2.8.7

Patched issue with POST submissions
* Submissions to pages with POST that had zero post arguments would bypass cache and invoke a rebuild of the already optimized page.

2.8.6

Patched issue with on-the-fly optimizations for sites hosted with WPMU DEV
* The typical 404 page served from nginx is different on WPMU, so the plugin was not detecting the ngnix environement and as such was not passing along the appropriate condtions for the API to format the code accordingly.

2.8.5

Patched issue with on-the-fly optimizations for sites in subfolders
* Handling was added for sites that exist within a subfolder (example: /blog/) — previously, the CSS/JS/Images were unable to be fetched due to a filename mapping issue.

2.8.4

API IP Addresses for Wordfence Firewall Conditioning
* A recent update to the API IP list had been corrupted.  In the event to deal with this condition in the future, we have added two fields to the data that is deleted when the plugin is uninstalled.

2.8.3

WordPress.com Hosted Sites now Supported
* The plugin is now set up to install on WordPress.com hosted sites (requires the WordPress.com “Business” plan or higher to install plugins).

2.8.2

Resolved output issue with 404 handler
* This patch addresses an issue, introduced in v2.8.0, where the 404 handler was being interrupted.
* Included in this patch is beta functionality for the Cloudflare ‘API Tokens’ feature, which is currently in development at Cloudflare.

2.8.1

Fixed issue of admin bar being cached
* This patch resolves an issue existing in v2.7 where the admin bar was being cached and served if a logged in user should hit a page that had acceleration enabled but did not yet have a cached optimized version of the page.

2.8.0

WordPress Multisite Network Compatibility (Using Subdirectories)
* Pegasaas now supports the WordPress Multisite Network feature, where you have a network administrator that manages multiple websites, or multiple versions of the same website, for testing development purposes. 
* Patched issue where sub-categories were not properly mapped for cache clearing or for being included in the pages accelerated total
* Patched issue where total number of pages accelerated was not calculated correctly, which in some cases prevented some installations from accelerating new pages/posts

2.7.4

Exposed PHP Notice
* This patch supresses a PHP Notice message that was displaying on some servers.

2.7.3

Microsoft Windows IIS Permalink Check / Exposed PHP Notice
* This patch resolves an issue with the Permalink check on installation, when the website is served by a Microsoft IIS system.
* In a recent update, certainly handling for query string arguments was modified. This in turn caused a PHP Notice to be exposed for those systems that display PHP Notices. This has now been resolved.

2.7.2

Debugging Improvements
* This patch includes further updates to resolve cache folder mapping issues introduced in 2.7.0

2.7.1

Cache Folder Bug Resolution For Installations that Reside in Subfolder
* This patch resolves a bug introduced in 2.7.0 for installations that reside within a subfolder where the “content” folder was not mapped correctly.

2.7.0

WordPress Multisite Network Compatibility (Using Subdomains)
* Pegasaas now supports the WordPress Multisite Network feature when using subdomains, where you have a network administrator that manages multiple websites, or multiple versions of the same website, for testing development purposes.  This new level of compatibility required changes across the entire plugin to properly map the location of cache files which needed to exist in parallel for multiple sites.
* Alternate “wp-content” folder location is now supported.

2.6.0

**Advanced Performance Metrics / Combine CSS and Combine JS Upgrade **
* Advanced Performance Metrics (Time to First Byte, First Contentful Paint, First Meaningful Paint, First CPU Idle, Speed Index, and Time To Interactive) are now available for each page displayed in the Pegasaas Accelerator WP dashboard for those using the “Advanced” display level. Intermediate will show a limited set of performance metrics.
* The Combine CSS feature was upgraded for Premium subscribers — you now will have the ability to specify the number of stylesheets to serve — by default, the system will build a single massive stylesheet for Guest API users.
* A new feature, Combine JS, performs the same mechanism for JavaScript as the Combine CSS feature does for stylesheets. This feature is currently tied to the “Deferral of Render Blocking Javascript”, but will be expanded in the future should someone want to combine JS but not defer it. By default, the system will build a single JS file, however Premium subscribers will have the ability to split it into up to 4 files.
* Additional support for a deprecated cURL error code has been added for those servers running older versions of cURL.
* Bug fixes to the dashboard that displayed “NAN” to the “PageSpeed Change” value once a PageSpeed scan was complete.

2.5.0

Script Lazy Loading
* For those users of the Guest API, we have opened the up basic script lazy loading feature.  If you have a script in your page that we’ve determined can be reliably lazy loaded until the user scrolls, then it will be.  You can, of course, disable this feature if you find it interferes with the operation of your page.
* If you have a premium subscription, you can take full advantage of the more robust capability of this advanced system.  For each script on your web page, you can specify if and when it is lazy loaded.  Be forewarned: lazy loading a script which has dependants can cause functionality in your page to break.
* This update also includes analytics opt-out code for pages that are requested via the ?accelerate=off query, which is typically used for Google PageSpeed Insights requests.
* Better support for sites protected with a password using HTTP AUTHENTICATION was included in this release.

2.4.2

Benchmark PageSpeed Scan Bug
* Resolved a bug introduced in version 2.4.0 where the system did not detect an existing Benchmark PageSpeed scan, which resulted with the interface indicating “Queued” scans, and then the request of unnecessary scans from the API.

2.4.1

Lazy Loading Scripts added to Standard Edition for Premium API subscribers
* Adding custom lazy loaded scripts was previously only available in the Pro Edition of the plugin. It is now avalable in the Standard Edition for Premium API subscribers.

2.4.0

Data Management Improvements
* This update dramatically improves the load time of the Pegasaas Accelerator dashboard (and by proxy, the entire WordPress system when using Pegasaas)
* Bug fix that resolved warning messages generated by the PegasaasInterface::admin_posts_column_content() function.
* Bug fix that resolved the modal overlay on first load of the Pegasaas dashboard, if using a mobile device.

2.3.9

Compatibility with WooCommerce API
* Previously, Pegasaas would append some code to the response for wp-json/ and wc-auth/ requests, causing the wc-auth requests to fail.  This release fully resolves this issue.

2.3.8

Cache and Data Management
* This update includes a few small improvements to the cache handling system related to mapping of URLs to the appropriate cache resource.

2.3.7

Compatibility (mod_pagespeed, Apache htaccess) Handling
* Instructions are automatically added to the .htaccess, disabling mod_pagespeed. This replaces the previous behaviour where the end user was required to manually disable the mod_pagespeed plugin themselves via their web hosting control panel.
* Added conditional satements to check for mod_header and mod_setenvif Apache modules to prevent a server error in the event that either of those Apache modules are not installed
* Created a mechanism to test whether the new .htaccess file will cause a 500 Internal Server Error, prior to saving the updated .htaccess file to the root.

2.3.6

Caching Related Issues Resolved
* This update removes the date/time check for cache, as this is no longer a relevant reason to invalidate cache as cache is already auto cleared through the cron system.

2.3.5

Caching Issue Bug Fix
* This update resolves a bug that was caused by an improperly assessed cache date for those installations which use a non-typical date format.

2.3.4

Support for WP Dashboard when Port Explicitly Declared
* This update adds support for a situation where the WP dashboard is accessed using a port #, such as https://somewebsite.com:443/wp-admin/

2.3.3

WP Engine Compatibility Patch
* Caching: Additional support has been added to clear invididual page level cache.
* Dynamic Resource Optimization: The WP Engine hosting platform was preventing the plugin from optimizing resources which were to be optimized on-the-fly. Modifications had to be made to the file naming convention (.optimized-css rather than .css-optimized)

2.3.2

Compatibility Patch
* Avada: The plugin will now resolve an issue where some Avada code was executing in a cart-before-the-horse situation in the main.js file. This resolves javascript errors resulting from incomplete rendering of the page.
* WooCommerce: Advanced support for WooCommerce Product Caterores/Tags has now been added to the Premium Edition.
* Flywheel: Initial support for the Flywheel hosting platform has been added. Flywheel maps the /wp-admin/ folder from a symbolically linked /www/.wordpress/wp-admin/ folder
* Cloudflare: Further support for the Cloudflare system was added to ensure that temporary cache is cleared when an optimization has been submitted to the plugin from the API.

2.3.1

Simplified operation of some features
* Deferral of Render Blocking JavaScript features have been simplified for the Standard edition.
* Deferral of Unused CSS feature has been simplified for the Standard edition.
* Removed the “recommended improvements” icon / popup
* Simplified up the “more” (vertical ellipsis) button beside the PageSpeed scores

2.3.0

Added suport for a new ‘Development’ mode in the Premium edition
* The new premium edition Development mode is supported with updates to this release.
* Contextual Help added to the top of the pages/posts panel
* Clarified the LIVE/Diagnostic mode with a new switcher at the top of the dashboard interface
* Added improved compatibility with W3 Total Cache

2.2.19

Database Performance Improvements
* Reduced the load time of the dashboard by half by adjusting a number of database queries.

2.2.18

Improved WP-CLI Compatibility
* Resolved an issue with the plugin that was caching output run by WP-CLI in rare situations.

2.2.17

Novice/Intermediate/Advanced Mode
* Added a new step to the installation wizard so asking web performance experience level. Interface is tailored to the level of experience — streamlining it for novice users.

Static Resources Cache Handling
* There is now a new tab in the dashboard labelled “Cache”, which provides the ability to view all of cached static resources, and their level of optimization. User can also delete individual items, as well as re-optimize the resource.

Improvements
* Resolved issue with installations being deployed to Bluehost as there was a recent change to the Endurance caching plugin which prevented the installation wizard from starting.
* Added improved support for subdirectory installations.

2.2.16

Custom Pages Installation Bug
* Resolved a problem with the installation routine when a user selected a custom selection of pages, that included the home page. In this scenario, all pages then had the acceleration enabled.

2.2.15

**Head, Footer, and Post Injections Compatibility **
* Resolved an issue where the “hefo_callback” was being suppressed by the Pegasaas Accelerator WP buffer capture system.

2.2.14

Compatibility
* When an image was being fetched for optimization, there was an issue that if the server did not respond with a source file, even though the file existed, a placeholder image of zero bytes was being stored.  This behaviour has now been updated so as to just return a 404 result and exit early with no optimization.
* We have changed how the plugin responds to conflicting plugins, so that third-party caching plugins are currently considered conflicting if Cloudflare is installed.  When more than one caching plugin is present (Pegasaas + one other) the ability for the system to succesfully fetch optimized pages is diminished.  We have plans to resolve this issue, but for the time being, it is best to consider other third party caching plugins not compatible in this scenario.
* At installation, we are now prompting for Cloudflare credentials if the system detects that Cloudflare is present.
* We have added compatibility with the “Accelerated Mobile Pages” plugin to allow mobile redirection.
* Additional support for Pagely hosting (through SSL detection) has been added.
* We are now detecting possible hung installations through the installation wizard.  If the system detects a possible hung installation, it will notify the Pegasaas team so that we can investigate, while attempting to retry.  If, after the typical initialization duration, the optimization request are not performed as anticipated, it will display a message indicating that the initialization did not proceed, that the Pegasaas team has been notifiede, and to initiate a support ticket.
* A new system to notify you when you are runing low on credits is now in place.

2.2.13

Compatibility
* Added support for permalinks that do not have a trailing slash /, and confirmed support for permalinks formatted in the /index.php/path/to/resource/ manner.
* Resolved the case of the system incurring a 500 server error when initialized on a site with a space in the document root folder (or parent folders).  The .htaccess contained two RewriteCond instructions which each contained a path that needed to be wrapped within quotes.

Lazy Loading
* Added ability for the user to define image paths to be excluded from lazy loading foreground and background images

Static Resource Handling
* Added handling for situations where static resources are not handled by the WordPress 404 system — previously, the plugin could not optimize CSS/JS/images if static resources were excluded from being handled by the WordPress 404 system.

2.2.12

Installation Routine
* Added support form that is now accessible in the event that the installation hangs
* Test for invalid SSL certificate and warn that installation cannot be complete until the SSL certificate issues is resolved
* Added new test for a non-existant .htaccess file, which attempts to create a .htaccess file if the environment supports it, based upon the permalink settings of the site
* Added support for installations that allocate 1GB+ of memory to PHP

Image Optimization
* Added support for installations that migrate from a website that uses a /~userdir/ 
* Resolved possible conflict of the lazy loading images code with other scripts that use boilerplate IntersectionObserver code

Caching
* Resolved an issue where the plugin was requesting optimized versions of pages on a POST request, possibly storing submitted data to a form if the form utility injected submitted values into the form.
* Added a new feature (Dynamic URLs) where the user can specify if they want query string arguments to bypass the cached optimized page.  This may be required for those installations that use a plugin which passes query string arguments in order to display a dynamic page.  With this new feature, you can also specify arguments to ignore, such as those that are associated with pay-per-click or tracking systems, that do not require a dynamically generated page.

2.2.11

Installation Routine
* New Step #1 which explains what the installation wizard does, and allows the user to choose their interface color
* Existing “Light” interface syle is updated with cloud background
* New “Plain” interface is more netutral than the “Light” interface.
* Updated final step of Installation Wizard simplifies how you choose which pages/posts to optimize, with a new “Advanced” option where the user can choose individual posts, pages, or custom post types
* If a user does not have enough credits to complete the basic installation, it will warn them once the installation wizard has been submitted.

Installation Bug Fixes
* Resolved an issue when the dashboard is being referenced via HTTPS but the website is set as HTTP in the WordPress general settings page.  This was causing installations to hang at 93% as the optimized page was not being saved due to an inconsistent “resource id”.
* Resolved an issue where a server side firewall existed, that was preventing the submission of large post data (the optimization request) by implementing a notify-then-fetch routine.

Builder Compatibility
* Added compatibility for the new Divi builder by excluding URLS from being optimized that contained the et_fb=1 or et_bfb=1 arguments
* Added compatibility for the Cornerstone (X) builder by excluding any URLS from being optimized that contained /x/, or were referred by /x/

2.2.10

Cache Management
* Added support for Pagely server side (Varnish based) caching system 
* Detect and alert user if “mod_pagespeed” installed on the server (as mod_pagespeed will conflict with Pegasaas functionality)
* Resolved isssue where incorrect subfolder paths were created in the wp-content/ folder, when optimized pages were returned from the API
* Added new feature where the user can choose to enable “auto clear” of page cache on a weekly or monthly basis

Memory Management
* Migrated the use of native page setting and page cache state variables stored in WordPress wp_options table to a pegasaas_page_config and pegasaas_page_cache tables, to avoid bloat to the wp_options table that can occur with very large installations

Usability
* Added a “Welcome Tour” video to the interface upon first installationAdded a check for a valid email on Guest API key request
* Added a new tab labelled “Tools” which now has options to “Enable All” or “Disable All” acceleration for each of the page, post, or custom post types
* Added post level configurations for all custom post types — previously, this was available only for pages and posts
* Added a new tab labelled “Changelog” which includes a list of recent updates
* Added a check for plugin being installed to a installation on “localhost” — system cannot be installed on “localhost” as there is no way to scan “localhost” or return optimizations or scans to “localhost” from the API
* Added ability for Developer Edition to ‘optimize on the fly’ if dynamically generated page (query string, logged in user, ecommerce) is detected
