    It might not work in WordPress 5.4.

    Fatal error: Cannot redeclare wp_cache_add() (previously declared in /public_html/wp-includes/cache.php:30) in /public_html/wp-content/plugins/memcached-redux/object-cache.php on line 18

    @jazir5 Sorry for the wait! Yes, it works with WordPress 5.4 in my testing. I’ve updated the plugin to reflect it.

    Please let me know if you run into any incompatibilities, though!

    @lukefiretoss This plugin works by placing the object-cache.php file into wp-content (see, and that might be why this error is showing for you.



    @lukefiretoss weird that you mention that. I’m seeing the same error on my side.
