Why bother the developers and delay the release of the Pro version?
What developers ??
Jo Ann, put Xampp or similar on your system, so you can do all your testing offline
in a controlled environment. That way if you mess around with things, you won't screw your sites up.
If you put the search term 'missing group information in GET request' into Google, it only comes up with this forum link.
Try putting part of the actual error message into Google's search box, if it still comes up with nothing, then the error is unique to yourself....
