Doing fine I guess. What a day!
Too many hacks and I waited too long for the main vBulletin upgrade. Like I said, if it ain't broke, don't fix it.
That upgrade section of the install program needs to be a bit more user friendly. On a fresh install, everything might be fine, but if you need to re-run install, some bullet-proofing is needed for those strange circumstances.
I have absolutely no idea why ppgal_stats was in my database unless it came in with 2.1 and if it came in with 2.1 then 2.3 should have been expecting to find it already in place.
Anyway, it's up and running and no errors are spewing forth from sql.
