W3 Total Cache improves the SEO and user experience of your site by increasing website performance, reducing download times via features like content delivery network (CDN) integration. (This is a Joke, this plugin will only destroy your website).
I tried this plugin because popular wisdom is that WordPress runs faster with caching. My site was still slow after installing this and even slower accessing the dashboard – but the problems persisted after I deactivated the plugin. Luckily I opened .htacess to check on something else and discovered a section of W3TC code. My site is running better now that I’ve deleted that code. Still not as fast as I want, but no more 503 errors!
I have tried this plugin with at least 5 different websites. For a while, things go well, but eventually the whole thing breaks. From error 500 to ghost pages and cache weirdness, this plugin has cost me at least 20 hours of frustration, troubleshooting, and repair.
One time plugin is working fine, but one day I try to load my site and got “This Page You Are looking for Has Not Been Found” … What? I can’t even deactivate it from the dashboard without getting an internal server error. So, I open my cPanel and FileManager and start looking for a problem, I know that is a problem on some plugins so I first delete W3 Total Cache and voila, site start loading fine.
Delete the W3 Total Cache plugin from the Wp-content/plugins folder.
Remove this line from Wp-config file – (define(‘WP_CACHE’, true) )
Delete advanced-cache.php, db.php, wp-total-cache-config.php, and delete the entire w3tc folder.
Check the .htaccess file; if you see any code added by W3 Total Cache, remove it.
If you have some problems with W3 Total Cache just open your cPanel/File Manager and delete this web destroying plugin. PCBunker does not recommend downloading and installing this plugin because this plugin will totally screwed up your site.
