 * Hello, I like your plugin but I am now getting the error
 * Fatal error: Cannot redeclare wp_cache_add() (previously declared in /home/XXXX/
   public_html/wp-includes/cache.php:27) in /home/XXXXX/public_html/wp-content/plugins/
   memcached-redux/object-cache.php on line 18
 * Is there anything that can be done about this?
 * Thanks

 * You’re not supposed to activate this like a normal plugin. This is a dropin plugin.
