WP Super Cache has to modify configuration files that WordPress uses, and 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 the following configuration files, so the plugin does not load:
wp-config.phpand delete the line that has the text
WP_CACHEin it. Also, do the same with the line containing
- Edit the file
.htaccess. It’s probably in the same directory as the
wp-config.php. You may need to “show hidden files” in your file manager to see it. Look for a line that says
BEGIN WPSuperCache, and then scroll down to
END WPSuperCache. You must delete any lines between those two.
- Delete the files
You should use the file manager provided by your hosting provider or an FTP tool to find the files on your host. You may not be allowed to edit the files because of their file permissions but your hosting provider should have documentation available on how to overcome this.
