I'm using Oxwall for a few days now and yesterday some functions stopped working. People can't change their avatar, drop down menu is not popping up if the cursor is over the icon. I can't select/activate a new theme or save custom CSS in the Admin Panel (nothing happens when I click on the buttons). Also tabs on profile pages and some buttons are not working (simply nothing happens). Is this something with Javascript? Because, if i'm going with my cursor over an broken object. Google chrome says in the lower left corner "Javascript://". I'm using the simplicity theme.

Google Chrome inspect gives me some errors like: 

My profile: SyntaxError: Invalid or unexpected token /user/Zadakine:2269

My Admin Panel: SyntaxError: Invalid or unexpected token /admin:1780

I hope somebody knows what the issue is, I can't use my site now :(
