Same here. This extension will make the WordPress admin impossible to use. I hope it did not break anything else :-/
Uninstall & remove all fiels as soon as possible!
Do not use this plugin.
The admin pages was covered with debug-boxes that was hiding menus, minimizing menus etc.
And even when uninstalled it still hade damaged some settings in the WordPress.
