XF 1.2 Weird javascript error

Whenever I try to promote a thread OR hover over the vistor's toolbar (inbox, user options, ) I get the following error in the attached picture below. java error.png

I've attached the error code also.

Promote a thread where?

If it's related to an add-on, post in the add-on thread for support.
It's not just an add-on problem tho. Happens when hovering over user tabs as well.

I tried disabling xenporta, to rule it out. I still get the error. Seems to happen when I hover over inbox or alert.
