    What does this mean?

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

    Query Monitor Alert

    Object Cache
    96.3% hit rate (9,051 hits, 352 misses)
    External object cache not in use
    The Redis extension for PHP is installed but is not in use by WordPress
    The Zend OPcache extension for PHP is installed but is not in use by WordPress

    Thank you for the clarification. I’m aware that this remains an issue after three months and I don’t need to be reminded.

    There are lots of things I want to fix and add to QM, but there isn’t enough time in the day. I’ll fix this as soon as I can.

    I wait for your update. Don’t forget 5.0 came out and I haven’t update, till I’m sure all plugins I use are compatible, incliding yours.

    Thank you for your work

    Hello again

    I just installed the Version 3.2.2, but I still see the message? Must I do something else? Must I activate or add any other plugin?

    Thank you for your work!

    This hasn’t been fixed. This really isn’t a priority at the moment.

    I have version 3.3 and I still get the error as follows:

    Object Cache
    94.6% hit rate (4,623 hits, 264 misses)

    External object cache not in use

    Opcode cache in use: Zend OPcache

    @keyuroz Which external object cache are you using?

    (@keyuroz)

    Well I do use the plugins for faster page delivery such as WP Rocket and AutoOptimize but they, I think, do not provide the object caching. Also upon reading several articles on the web regarding the object cache, I understand for WordPress we need to have either Redis or Memcached to enable external object caching, which is not at all installed or I may have no idea if it is from the server side.

    The site is using PHP 7.0 however memcache and memcached PHP extensions are not ticked on (From the cPanel > security > Select PHP Version). I could show the screenshot but I guess there is no means to do so here.

    Do you recommend me to tick-on the memcached to enable the external object caching or should I ask the hosting if they have Redis installed for this server to install the ‘Redis Object Cache’ plugin?

    Please advise.

    That’s really your decision to make. The reason QM flags up the lack of an object cache is because it will give you considerable performance benefits, but you might want to check with your host to see what they say.

    @johnbillion Thanks

    I am still seeing this error with Comet Cache working perfectly.

    I have this error occurring:

    External object cache not in use

    The Redis extension for PHP is installed but is not in use by WordPress
    Opcode cache in use: Zend OPcache

    Here I’m getting:

    “Object Cache
    97,5% hit rate (6.358 hits, 164 misses)

    External object cache not in use”.

    What does it means?
