Do you have the new Visual Editor enabled? Cause there is a jscript conflict which blocks one or the other. If it is enabled, disable and see if the Tags start working again. If so, then you know the problem. Were you to involve the Tech Team they would likely comment out your UserTags to keep VE working.

When this happened on Bloons Conception it took me a weekend to niggle the code back to working order.

Another culprit may be the code you are using to customize the On This Wiki level of your wiki-nav. Try editing that out (shouldn't have it anyway, it is a TOU Violation).
