I get the same thing with the file you gave me, keeps sending me to an empty cart also with that new file if im not logged in and i try to buy when it ask me for the login also it emptys the cart, also the order of things are the default from the checkout wizard i just moved the button down but even if it was up was the same thing, i also notice that the orders get kind of mess up when working with a template if i work them on a blank page the orders are difrent
