 * Upon activating the plugin I get the following error:
    Fatal error: Cannot redeclare
   wp_cache_add() (previously declared in /home/mysite/public_html/wp-includes/cache.
   php:24) in /home/mysite/public_html/wp-content/plugins/memcached-redux/object-
   cache.php on line 16
 * No other active plugins on the site and I do have pecl memcached and memcache
   installed on the server. Any advice?

 * Don’t activate it, move object-cache.php to wp-content/
