Okay, I'm having a problem that I can't seem to find the answer for (though I may have missed it), and it's similar to this one...

I installed Nuke 8.1, and everything was running fine. I was having difficulty with a self-written module, and suspected that something in 8.1 was giving it issues, since the same module had worked fine on 7.9...in my frustration, I did a stupid thing, and uploaded 7.9 in place of the 8.1 install.

(Incidentally, the self-written module worked fine, it was an unrelated issue)

Now, whenever I or any of my admins tries to edit any module (FAQ, Encyclopedia, Forums, etc), I get an "Access Denied" error. This does not happen, interestingly, with the Content Admin link; it does happen with Coppermine. I've completely deleted my Nuke installation and reinstalled back to 8.1, then restored the SQL tables (there's a lot of data we can't really afford to lose), and the issue persists. I also deleted all my Admins and recreated the God account, with the same issue.

Any ideas?
