Maze,
I don't know 'what' is the cause of our probelms. I only know that before this 'upgrade', I never had a problem. Again, today, users disappeared, but when I check table, NONE are corrupted.
I honestly don't know what to do (which is why I came here)
IP seems to say 'roll back to previous version', or take out the ability to do searches. But does that means there's a problem with 6.3.2, or with something else (since our database claims it's not corrupt on multiple checks)
