Tabs won´t work

I have set up Tabs GK4 but they won´t work, nothing happend when I click on the tab. I use Tabs GK4 on other sites and it works there but not when I use Musicity. I have taken a screenshot of which tabs I am talking about:

The Facebook tab uses the module FB GK4 och the Twitter tab uses the module Tweet display back.

Here is my site you can test it there, the tabs are to the right: http://ffatest.se/

Hi

Please try to force the use script option on "Advanced settings" of GK Tabs GK4 module.

Cheers

It is already set to "Force enabled".

The module worked fine att first but after a few days it stopped working.

Can you please help me with this problem!

I discovered that the tabs works when I am logged in but not when I am logged out.

After I did this:
