That sounds like Polish, but I could be wrong. Have you checked your language settings, and whether you created that wiki in Polish by accident?

Some of the interface have a tendency to get "stuck" if they get cached at the moment someone with non-EN language settings views it, but that's usualyl not the edit button.
