Hi.
My store was working good with real products but i disabled all of them and added two virtual products.
When i try to buy something, i cannot go to the payment module, because on the third step it always returned me to the checkout_payment page.
The problem is the script is looking for a shipping address and it's jumping to the step one, but is free shipping it goes automatically to the second, and it doesn't allow to pay because in the third step it goes to the second (etc...).
I need to disable this. Where is the script that control this?
Can someone help me with this issue? thanks a lot.
(my store is version 1.2x)
