WP-Super-Cache activation errors

I have to set up the cache on a WordPress project, which is already on "support mode" in the agency for a while.

The plugin WP Super Cache was already installed so I activated it, to setting up it.

I work locally on dev mode and the project have a preprod and a prod environments.

When I activated it, the following error messages appear in back-office :

Warning: include(/var/www/xx/xx/xx/xx/xx/xx/wp-content/plugins/wp-super-cache/wp-cache-base.php): failed to open stream: No such file or directory in /var/www/wp-content/plugins/wp-super-cache/wp-cache.php on line 65

Warning: include(): Failed opening ‘/var/www/xx/xx/xx/xx/xx/xx/wp-content/plugins/wp-super-cache/wp-cache-base.php’ for inclusion (include_path=’.:/usr/share/php:/usr/share/pear’) in /var/www/wp-content/plugins/wp-super-cache/wp-cache.php on line 65

Warning: include_once(/var/www/xx/xx/xx/xx/xx/xx/wp-content/plugins/wp-super-cache/ossdl-cdn.php): failed to open stream: No such file or directory in /var/www/wp-content/plugins/wp-super-cache/wp-cache.php on line 82

Warning: include_once(): Failed opening ‘/var/www/xx/xx/xx/xx/xx/xx/wp-content/plugins/wp-super-cache/ossdl-cdn.php’ for inclusion (include_path=’.:/usr/share/php:/usr/share/pear’) in /var/www/wp-content/plugins/wp-super-cache/wp-cache.php on line 82

Looking in the file wp-cache.php on lines 65 and 82, it says that :

include(WPCACHEHOME . 'wp-cache-base.php');

Path ‘dirname(FILE).’/…wp-cache-base.php’ not found Include expression is not resolved

include_once( WPCACHEHOME . 'ossdl-cdn.php' );

Path ‘dirname(FILE).’/…ossdl-cdn.php’ not found Include expression is not resolved

So I was thinking about changing the path. However, this is bothering me because I am afraid that this action will be potentially a troubleshooting cause when the plugin will have to be updated.

I have no ideas how I can fix it. Uninstall and reinstall the plugin ? Use an other plugin to manage the cache?

Thank you in advance for your answers. Have a nice day!

WP Super Cache puts the below line in your wp-config.php file. Remove the line from your wp-config.php file and reinstall and reactivate the plugin.

define( ‘WPCACHEHOME’, ‘/home/USERNAME/public_html/wp/wp-content/plugins/wp-super-cache/’ ); //Added by WP-Cache Manager

I encountered the same problem after moving my Wordpress directory to the root of my site. If you get the problem and can't deactivate the erroring plugin, go to your /wp-content/plugins/wp-super-cache and remove or rename the directory. This will manually deactivate this so you can install a fresh instance.
