FAQ
Why it always tells me that I’m failed to answer the quiz?
“Failed to answer” means the plugin encounters some problems to get needed information. If you think it’s my fault, feel free to inform me. 🙂
Why the plugin can’t be removed?
Freetype, a text renderer, keeps the font file handle open, causing Windows and other OS to lock the font file. Deactivate the plugin before you update it.
