 * Fatal error: Cannot redeclare wp_cache_add() (previously declared in /public_html/
   wp-includes/cache.php:30) in /public_html/wp-content/plugins/memcached/object-
   cache.php on line 23.
 * UPD:
 * To plugin author:
    Please make the “copy the file to wp-content instead of activating
   it in the backend” message more attractive!
 * Works. The website speed become A BIT faster, but still too slow (WP 5.7, no 
   other cache plugins).
