Ubermenu had Google Map Api enabled:
Load Google Maps API
If you are already loading the Google Maps API, or if you do not need Google Maps in your menu, you can disable this.
This removed the double call to Google Maps API. Now we need to resolve the other.
Error: Bootstrap’s JavaScript requires jQuery

Line 6
You should try disabling all non GD plugin to see if any of the is causing that error. Than reactivate one by one to find out which one exactly was the culprit.
Thx
Just FYI, Ubermenu will add an avarage of 150 db queries per page load (more than doubling original queries).
I love the menus that you can make with it, but they also slow down your website a lot.
