 * 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](https://wordpress.org/support/users/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](https://wordpress.org/support/users/lukefiretoss/) This plugin
   works by placing the `object-cache.php` file into `wp-content` (see [https://wordpress.org/plugins/memcached-redux/#installation](https://wordpress.org/plugins/memcached-redux/#installation)),
   and that might be why this error is showing for you.

 * [@lukefiretoss](https://wordpress.org/support/users/lukefiretoss/) weird that
   you mention that. I’m seeing the same error on my side.
