The site was fine yesterday. Today in Firefox and Chrome all the forum posts are totally different. Different text, different options, new stuff I’ve never seen before (was likely hidden) etc.
It looks awful and makes reading posts almost impossible.
Old server hardware died and we are moving to a new one.
We are also enabling https on the new server, and that seems to screw up the style because of some non-SSL links. I think I have fixed all those links. Post here if you still see issues.
