That is all very odd because the server migration wasn't performed on THIS server, but the one hosting all the other sites. I still haven't tracked that issue down.

That said, I have gotten a few errors like that here, and they don't make any sense.

If you haven't yet, for log-in problems, please go to My Stuff > Cookies and "expire" them and log back in. Let me know if it's still an issue.

And please try to copy/paste any error messages you may get here so I can track down the source of any problem -- thanks!
