I was so happy and now?

Hi @dgswim

Sorry to hear this, but we no longer maintain this plugin. The best you can do is try to manually copy the latest version of the memcache object cache implementation to your wp-content folder and see if that helps. Our plugin is just a handy but outdated wrapper around this implementation: https://github.com/Automattic/wp-memcached/blob/master/object-cache.php

Hi, I′m confusing, are you still maintain the plugin or not?

There is an update just 7 days ago…..

No, I am no longer using it. I did get it working in the beginning but could not get it to work again. I had to stop spending time on it.
