It was working before I went to 4.4.2 on a 4.0 WP site. just after I sent this note 4.4.3 was available. I was eventually able to get the site back up and running, I had to disable the plugin and reinstall. Once I had did this and renamed me .htaccess file the Hide back in started working. I now have to go back and reset up the plugin.
The plug in seems to be causing issues when trying to customize themes, The tool will load but then non of the drop downs work until I disable the plugins.
