I'm not exactly new to wikia, but I'm guessing this is a newbie problem.
A couple of hours ago I decided to change my avatar. I always find that if I change it to one of the wikia ones first, then save. Then upload my new avatar, it uploads quicker. Every time I try, it does the same three bar loading screen for ages. Nothing happens. I don't know what I'm doing wrong. It lets me change to all the wikia ones fine without a problem. I can't even re-upload my old avatar.
