Displays a colored environment indicator in the admin bar.
Don’t Mess Up Prod helps developers and content managers quickly identify which environment they’re working in by displaying a colored indicator in the WordPress admin bar. Hopefully this prevents messing up production ????

FAQ
How do I configure which environment I’m in?
The plugin detects your environment automatically in two ways:
- URL Matching – Configure environment URLs in Settings → Don’t Mess Up Prod, or using the
dmup_environment_urls filter
-
WP_ENVIRONMENT_TYPE – Set this constant in your wp-config.php:
define( ‘WP_ENVIRONMENT_TYPE’, ‘staging’ );
How do I customize the colors?
Use Settings → Don’t Mess Up Prod to set colors, or add a filter in your theme’s functions.php or a mu-plugin:
add_filter( 'dmup_environment_colors', function( $colors ) {
return [
'local' => '#17a2b8', // blue
'development' => '#6f42c1', // purple
'staging' => '#ffc107', // yellow
'production' => '#dc3545', // red
];
} );
How do I control who can see the indicator?
By default, users with the publish_posts capability can see it. Customize this:
Role-based access:
add_filter( 'dmup_minimum_capability', function() {
return 'edit_posts'; // or 'manage_options', etc.
} );
Specific users only:
add_filter( 'dmup_allowed_users', function( $users ) {
return array_merge( $users, [ 'johndoe', 'janedoe' ] );
} );
How do I add environment URLs for quick switching?
Configure environment URLs in Settings → Don’t Mess Up Prod to show a menu with links to other environments, or use the filter:
add_filter( 'dmup_environment_urls', function() {
return [
'local' => 'http://yourproject.local',
'development' => 'https://dev.yourproject.com',
'staging' => 'https://staging.yourproject.com',
'production' => 'https://yourproject.com',
];
} );
