All righty, though I'm warning you, you'll probably find a gazillion things wrong with the layout that aren't related. XD I'm pretty sloppy, and there's a lot I have on there from back when I was first learning about vB that I haven't updated.
The account is vB.org Test Account, and the password is vB.org.
The only problem (other than the look of the thing) that I myself am encountering is that Quick Edits delete all line breaks. However, many members are experiencing the things clubplanet described in Post #2.
QuickEdit's do indeed kill line breaks. Advanced editing does not.
I'm not seeing any of the issues I was having with my forum though outside of that and I'm on the PC that was having all the troubles.
btw, that account doesnt have thread delete rights so you may want to remove the test thread I created. Tried to do it in a place where your members dont visit.
Just a total guess here but I would run a suspect file diagnostic on the forum and see what comes up. It's possible that whatever file thats controlling that didnt get uped correctly.
