Hello gnfb,
It is likely that your hosting provider has installed and enabled our cache plugin across their hosted WordPress sites using the ‘Mass Enable’ feature of our WHM plugin/cli script. You should see a message displayed in your WordPress dashboard explaining this if it is the case.
‘Mass Enable’ will also only install our plugin on WordPress sites that are not currently using another caching plugin. Your site should be loading much faster (for non-logged in users) now that it is being served from cache.
If you have any questions or concerns please do let us know, we are always happy to help.
Regards,
-Michael
