To help me isolate the strange instability issues with the forums that started on Sept 16th, please note that at the moment I've reverted the database back to the Sept 15th copy. This could mean two things:
1) If the problems with the forums are fixed as a result of the reverting, this means I'll have to stick to this copy of the database, and posts made after Sept 15th are lost unfortunately.
2) If the problems still persist, then I'll be restoring the latest copy of the database, which is Sept 24th, and we go from there.
Due to the uncertainty at this point, you should bare in mind that any posts made on CF now may be flushed if 2) turns out to be the outcome.
Sorry for the inconvenience, but this appears to be a necessary step for me to diagnose the problems, which specifically are:
1) A vBulletin database error instead of the actual page you're viewing
2) Slow or inaccessible pages.
Please post any issues you experience with the forums at this point in this thread.
