I'm an administrator on another wiki. I just deleted a page with the intention of immediately restoring it, in order to delete a revision that violated Wikia's Terms Of Use, but when I try to restore the page, I get this Message: =Permissions errors=

You do not have permission to undelete this page, for the following reason:

You cannot undelete this page as there is no existing page with this name and you are not allowed to create this page.

Firstly, that last sentence makes absolutely no sense. Secondly, why is this happening?
