Installed as any other WordPress plugins.
Followed the instruction add the short code to the footer and run.
Guest what, believe or not full screen of error messages!
It even screws up the language system. For me I am using Chinese version WordPress, all the Chinese words become unreadable. Because of this I can not login the WordPress's back-end to uninstall this plugin. I have to go the the file system to delete this plugin folder.
If anyone who wish a try, I suggest you don't try to do on your live site!
Good luck guy
