New version not working after update, getting permission error no matter what permissions or owners I use, tried deleting the plugin completely and reinstalling it from scratch, tried the empty file, tried deleting the file and having plugin re-create it and I always get this same error message and viewing page src, the plugin is not running
Failed to update your /wp-content/advanced-cache.php file. Most likely a permissions error. Please create an empty file here: /wp-content/advanced-cache.php (just an empty PHP file, with nothing in it); give it permissions 644 or higher (perhaps 666). Once you’ve done this, please try again.
