Backend script issue

Hi,

I have an issue running jQuery scripts in the backend (like showing submenus, adding a feature image etc.) on every backend page where the NextGEN Gallery is loaded. I tried disabling all the plugins and I reactiveted them one-by-one and that’s how I narrowed down the problem.

In the Chrome console I get this every time I open a page where NextGEN Gallery is loaded:
