    What does this mean?

    I have wp opcache installed and it appears to be working. That plugin shows 99.98% hit rate.

    Thanks for the message. I’ll take a look.

    The cause of this message is because QM checks the return value of the wp_using_ext_object_cache() function, which usually only returns true if there’s a wp-content/object-cache.php file in place. With the Zend OPcache extension this file isn’t required, and this function returns false.

    I’ll tweak QM a bit so it doesn’t show this message when the Zend OPcache extension is in use.
