Maybe Wikia is just bugging out? I can't think of any conditions where that wouldn't work. Maybe check back later, and if you still can't edit, contact Wikia staff. I'm not an expert on this matter, so I'm sorry that I don't know what to do. Just know you aren't blocked or anything, so don't worry too much.
Well, we've warned them about their behavior numerous times, and the whole child pregnancy thing on Peanut Otter's Disco this morning was just a step too far. We banned them for a week, hoping they'd improve their behavior, but we may have to go for longer if necessary.
