I just noticed this morning when I try to click on “quote” to quote a post, the Board asks me for my Username and Passwrod, and tells me they are invalid and will not let me quote. Yet, when I do a “Reply” or “New Thread”, it works. I tested this on Netscape 4.7, and IE 5.5, and cleared all cookies, and re-logged in, and even tried it on 3 PCs. No luck. Are we having a vBulletin hiccup?
I don’t know - I didn’t have any problem.
I get that every now and then. Usually it goes away in a few minutes. I have a half-assed, not-backed-up-by-facts theory that vB is sorting it’s user database or something. How long has this lasted for you (hours? minutes?)

It has magically fixed itself now. I have no idea why, but this thread is dead nonetheless. Sigh. Looks like I wasted bandwidth.
Nah, you are never a waste of bandwidth, my dear. 
If you log into one vBulletin board, you’re automatically logged out of all other vBulletin board you might frequent. Apparently, your first action back here was a quote, so it told you then that you weren’t logged in. After that, you were, so it was no problem.
Just on the off chance that you’ve been frequenting any other vB boards, of course.
