I am using theme Ethos 1 and have W3 total cache plug-in installed.
Lately this plug-in has been causing my site to slow down a lot. on GT metrix my site speed is only 68% and most issues are related to ‘leverage browser caching’ and CSS.
I want to change the plug in and try other good well known plug-ins but I see WP super cache and WP fastest cache are not tested with Ethos 1.
Are they still safe to install?
