This extension adds a button in your admin area to flush OPcache easily. It supports both memory and file caching transparently.
If this is a multisite installation, it only shows up in network admin dashboard.
There is a submenu page with all statistics about OPcache. There is an option to automatically flush OPcache when a WordPress or plugin update occurred.
The statistics tabs relies on https://github.com/wp-cloud/opcache-status
If you want to add a translation in your own language, you can use flush-opcache.pot located in languages folder and send me by email.
