I upgraded our web servers to PHP 5.5.30 with opcache and since APC is no longer necessary I was trying to remove the plugin but I am getting an error while trying to remove the cache store instance so I can uninstall the plugin. I already removed all known cache definitions related to the APC store.

PHP Fatal error: Call to undefined function apc_cache_info() in ../moodle/cache/stores/apc/lib.php on line 257, referrer: http://../cache/admin.php?store=local_apc&sesskey=12345678&action=deletestore

Thanks!
