Uninstall WP Cache manually, in an emergency

WP Super Cache has to modify configuration files that WordPress uses. On rare occasions, the modifications fail, which will cause an error when the website is loaded.

If you cannot load your site to remove or deactivate WP Super Cache, you will have to edit some files so the plugin does not load. Follow these steps:

1. Use the file manager provided by your hosting provider or an FTP tool to find the files on your host.
2. Edit wp-config.php and delete the line that has the text WP_CACHE in it. Also, do the same with the line containing WPCACHEHOME.
3. Edit the .htaccess file, which is probably in the same directory as the wp-config.php. You may need to “show hidden files” in your file manager to see it. Delete any lines between BEGIN WPSuperCache and END WPSuperCache.
4. Delete the files wp-content/advanced-cache.php and wp-content/wp-cache-config.php

If you do not have the right permissions to edit the files, check your hosting provider’s documentation on how to adjust your permissions.
