Edit Mode broken

Hey there,

I updated my Concrete5 site to 8.2.1. Since then I am not able to add pages anymore. The page will be added as draft and can be published, but I cannot edit attributes or add blocks.
The Chrome Console prints out:

Uncaught TypeError: html.addClass is not a function
    at ConcretePanel.d (app.js:1)
    at ConcretePanel.show (app.js:1)
    at ConcretePanel.toggle (app.js:1)
    at HTMLAnchorElement.<anonymous> (app.js:5)
    at HTMLAnchorElement.dispatch (jquery.js:4)
    at HTMLAnchorElement.r.handle (jquery.js:4)
    at Object.trigger (jquery.js:4)
    at HTMLAnchorElement.<anonymous> (jquery.js:4)
    at Function.each (jquery.js:2)
    at m.fn.init.each (jquery.js:2)

The website is:
http://saskiabrueckner.com

The newly added subpage, which I want to edit, is:
http://saskiabrueckner.com/index.php/system/references...

Does anyone of you know how I can get my page back working?

Thanks a lot,

Saskia
