Ahh, I understand. I thought it was a wiki about someone's shop. I've restored the wiki.

You can't rename categoy pages, you just remove them by making sure there are no articles with that category, and delete the category page (if there is one)

But in this case they are hidden categories, so I'm not clear on how to remove them. I suggest you ask on the forums.
