I can't change, undo, rollback or anything for my Wiki nav bar. I replace the whole content with nothing, use source code from previous revisions, even click to edit it, make no changes and preview and it still says it is too wide. It could just be a glitch, but could someone please check they can edit it OK on this wiki?
