I was able to add to cart with Firefox 11 and in IE9, although the template is broken in IE.

The weird thing is that on 1 desktop PC, the add to cart button works fine, and the ADDED to cart pop up works fine.

But on my other PC in none of the browsers the ADD to CART button works, and on my laptop it doesnt aswell.

Im getting the following warning in firebug :

And choose to go to the shopping cart, after then, the product add to cart popup is working fine...

But after clearing browser cache, the same problem happens again, that the add to cart button is not working anymore
