What is endurance page cache
The problem is solved. You might ask, what plugin is endurance page cache?
Endurance page cache is a caching plugin from Bluehost. If you are using Bluehost hosting, it will be installed by default. If you are using other hosting and want to use it, you canGo to github to download。
The workflow of endurance page cache is to convert PHP files into HTML files. When a user visits, it serves the HTML file, thus avoiding PHP execution and reducing server load.
Naiba tested this plugin and found nothing special. It may require Bluehost hosting to work effectively. Therefore, it is recommended that non-Bluehost users who need a caching plugin consider more popular ones, such as WP Super Cache.
