I installed BPS Pro, then tried to reactivate W3 Total Cache. It came up with this error:
/home/accezz/public_html/wp-config.php could not be written, please edit config and add:
define('WP_CACHE', true); before require_once(ABSPATH . 'wp-settings.php');
Is that something to do with file locking? If I want to update plugins or themes, or activate them, do I have to turn something off?
