XF 2.1 Problem with Javascript

[mrx123]

Hey guys,

everytime if I want to change the style or open for example the user settings tab I got this error:

Oops! We ran into some problems.
Oops! We ran into some problems. Please try again later. More error details may be in the browser console.

I think there is a mistake in core-compiled.js:44:349

This is the Javascript file which is shown as error in the console.

We would need to know what the actual error is inside the console. Chances are though that something like a browser extension or an add-on is causing the problem.
