This site has been up for a month and I still cannot find a solution to this problem. I am using the Restaurante template and did the install via the site shaper. I have chosen to use the S5 Dropdown cart versus the column cart. I have spent much time on this issue and cannot find a solution. I have checked the installation instruction countless times and have reinstalled countless times. Ajax is turned on in VM. When you first turn it on ajax will update the cart until you leave the page. Then it will do nothing when add to cart is clicked. This is in Firefox. In IE it will not work at all and takes you to the checkout page. I have tried both carts with the same results. In IE I get an error message .
Message: 'GB_ROOT_DIR' is undefined
I believe that this error is related to the greybox which I have since turned off.
The URL for the site is www,tomscarcarecenter.com
Please help! The lack of Ajax is killing me and my client is not happy.
