Products wont add to cart

Hi,
I've set up a few products using the Furniture Store template but when I press "add to cart", nothing happens.

Can someone give me an idea of what is going wrong?

Your server returns "406 not acceptable" to ajax request when you click add tho chart button. That request works with json format data. You need to configure that in Apache to allow json.
