I have a magento website that is using Belvg Gifts extension but when the extension is active ite redirects to cart page when you are filling information on the onepage checkout step.
I check the errors using firebug console I get the following
POST http://www.floridawinestore.com/checkout/onepage/saveMethod/ 403 (Session Expired) prototype.js:1530
I conctacted the developer of the extension but said it works well but even when I install it using default Magento template it does not work. I have also tested with sevaral other templates but the same thing.
Here is the extension

If someone can help solve fix this extension I'll greatly appreciate
Thanks
