This plugin is an ABSOLUTE NIGHTMARE!!!!!! It took me six hours to repair the havoc it wreaked!
After installing it, my website was completely unresponsive. It was totally NOT THERE. When I went into the site via FTP, I deleted the plugin. After deleting I thought all would be fixed. Boy, was I wrong!!
The entire wp-settings.php file had to be restored from backup. Once that was restored I had to pick through every sub directory inside the plugins directory to look for remnants of the deleted plugin. It left behind a docs sub directory and a css sub directory. Once I renamed those directories so that the function call in the wp-settings.php file couldn’t find them, all was well.
One lesson learned from this…make sure you have a current backup before you install plugins you are not sure of.
