If you have ever installed a WordPress plugin or updated one only to find out it crashed your website, and given you the dreaded white screen of death, rather than look for your backups to restore there is a very fast and easy way to fix it all back to normal. How? Well using a free FTP program called Filezilla.
Often during troubleshooting, many sites will recommend deactivate all plugins and activate them one at a time. What can happen is sometimes you get locked out of your WordPress admin panel, so you can’t even deactivate the plugins the usual way.
I had this happen to me the other day when upgrading W3 total cache, it said the update failed and my site just looked strange as like the template was not loading correctly. I knew straight away that it was a rogue plugin.
w3 total cache error: some files appear to be missing or out of place
The error I was constantly getting was:
W3 Total Cache Error: some files appear to be missing or out-of-place. Please re-install plugin or remove /home/content/16/8282516/html/**/wp-content/object-cache.php
Tried to reinstall W3 total cache, didn’t work, tried to uninstall, but no good. Then things really went pear-shaped, I was unable to log back into WordPress.
Manual Disable Deactivate All WordPress Plugins
A quick way to disable all your WordPress Plugins is to rename the plugin folder using FileZilla or your Hosts FTP file manager.
Inside wp-content folder, you will see a folder called plugins. WordPress stores all plugins here, which are installed on your website.
Right-click on the plugins folder and select Rename. Change the name of the plugins folder to anything that you like for example “plugins.deactivate”. Once you do this, all of your plugins will be deactivated and hopefully, you can now be able to log into your website.
Once you do that, go back to your /wp-content/ folder and rename “plugins.deactivate” back to plugins. You can now reactive each plugin one at a time to see which may be causing the issue.
If you get locked out will a WordPress plugin error again just log back into your favorite FTP program and rename wp-content/plugins folder one more.
WordPress Manual Rename Plugins to Deactivate
Another way is to one by one rename the Plugins in wp-content/plugins/plugin-name
This process is more time-consuming but enables your site to run as it should without disabling all the plugins in one hit.

How to Disable W3 Total Cache Error with FileZilla
So once I worked out it was W3 Total Cache that was the issue I had to manually uninstall w3-total-cache
Download Filezilla its free and install it, or you can use your website hosts file manager. Navigate it to your website and start to manually delete the following files
w3tc-config, db.php, advanced-cache.php, object-cache.php in your main site folder wp-content.
Also delete the offending plugin in my case it was w3 total cache. This plugin is found at wp-content/plugins/w3-total-cache
w3 total cache plugin conflict
I have total removed w3 total cache now and why it conflicting who knows? It’s either the theme or another plugin but even after a few weeks I reinstalled and it was still crashing. Time to get another blog speed up the plugin.
