I'm off to my other job for the day!
No problem
Now, find the files that contain _NOPERM
(that's why you needed the local copy)
I don't know how many files there are that contain _NOPERM
but hopefully one of them is the file you also see in the address bar (site.com/user.php or something)
Open that one first and find the section that shows _NOPERM
Try and understand the logic that's going on in that file, otherwise, let us know.
(if i have my internet this weekend I'll try and download XOOPS 2.2.5 to my local PC, to help you a bit more)
