Menu won't expand after login

For some reason the menu doesn't expand after login. Before login it works fine on all browsers but after login the menu won't expand.

Any thoughts what the cause could be?

Hi,

Thanks for the fast reply I've made an account for you. I tested your account and it seems that it does work when you're just a registered user. Then I put your account in the superuser group and it stops working after login.

How can I send you a pm with the login details?
