Have you tried logging out, waiting a bit, and then logging back in? This has happened before and sometimes it is just a mix-up on the server's end. Logging out and waiting gives it time to "catch up" and recognize the correct status of your account.

Also, that particular wiki might have restricted edit permissions for new and anonymous users. If so, you will have to wait a certain about of time before you will be able to edit.
