Vielen Dank für das nützliche Tool. Ich benutze es regelmäßig seit vielen Jahren, um den Opcache mit einem Klick zu löschen. Auch die Informationen zu der Belegung des Speichers finde ich nützlich. Ich bin sehr zufrieden mit dem Plugin! Thank you for the useful tool. I use it regularly for many years to clear opcache with one click. I also find the information on memory usage useful. I am very satisfied with the plugin!

Author was very rude at support.

A must have plugin

By dotker on September 15, 2020

Everyone really needs to make sure php opcache is enabled its often overlooked but the speed improvements it gives is significant. This plugin simply gives an easy way to flush the php opcache easily and its great at what it does!

Works perfectly

Works perfectly, I like the statistic's panel (even if not really necessary :p ) In the settings, it might be better to enable "purge on update" as default, what do you think about it ? Thanks for this plugin, Regards
