It seems that we have two different problems, that may or may not be related - accessing of the server, and posting/messaging functions.
The upgrade may fix the posting functions if they are not related to the server IP issue.

I may have to take the board offline when I do the upgrade tonight when I get home (after Midnight eastern time).
Hi Griffin, did you do the upgrade?

I think that the 500 error is an issue at the Apache/server level, and the submitting of ANY form whose contents include "ht*p://" is forbidden. This is most likely an anti-spam measure to stop scalpers spammers from increasing their Google PageRank by polluting your/our site with links to theirs, or a security measure to prevent cross-site scripting attacks.

EDIT: in other words, I don't think it's a vBulletin issue.
