Mobile menu/maxi menu and Template Creator CK

We have 2 identical sites (set up/templates etc) and the one site runs fine (whatcom.kidinsider.com) but the other site has this issue regardless of everything we tried - skagit.kidinsider.com The menu disappears and the mobile menu tries to load. We currently have the mobile menu disabled on skagit.kidinsider.com and hope that maybe we can arrange a general time/day that you could review it. Leaving the menu not working for a time is not a good option.

you will need to disable the compression in your websites so that I can inspect the source code
