The problem is with Template:Navbox. The template uses itself, and therefore Template:Navobx uses Template:Navobx, which uses Template:Navobx, which uses Template:Navobx, and so on and so on, so the server just throws an error and ignores the template.

You need to either create Template:Navbox on your own, or copy its source from another wiki.
