I am trying to edit the Wiki Navigation on my wiki, but I have a problem. I am trying to add new links and tabs but it always has an error: "Level 2 menu is too long". Even though I delete all the code from the page, it still has this error. I can't belevive that the error is still there when a blank the page to nothing.
