Further to my paniced posting earlier, I reinstalled 2.2.0, copied over my data.fs* and various products and everything fired up fine but i did one experiment (following on from Chris) - i didnt install zdiscussions. This resulted in major oids errors and my broken zclass as before/ install zdiscussions and bingo i am back in business. so. two questios:
1. why does my zclass appear to require zdiscussions when it is not based on it?
Not sure on that...
2. does 2.2.4 contain some parts of what was previously the standalone zdiscussions product?
No. The only thing I could think of is maybe some change in the way products are registered or something that affects ZDiscussions badly. I'm just guessing here. Have you tried going from 2.2.0 -> 2.2.1 or 2.2.2? If you see the same thing on one of them, that would narrow it down and we could look at the diffs between those releases and see if anything looks suspicious...
