Wiki editing mystery

http://danbooru.donmai.us/wiki/show?title=gothic_lolita

When I try to edit this wiki it returns a page with "no title specified", I can edit other wikis though, it only happens in this one, I think, I hope.

Does it work for you?

I tried to edit it and got the same error.

Results replicated.

...

Do you still see this issue?

Yes.
