I am very disappointed with wp-e-commerce at this point. Every time there is an update I spend hours trying to fix things the update broke.
Going to 18.104.22.168 hasn't been any different. I simply cannot get the cart to show any items in the cart once I go to checkout. They show in the widget on the left sidebar (where I put it), but going to the checkout page it always says the cart is empty.
I have tried multiple times to clear the theme cache, update, rollback, update etc. all to no avail.
I originally tried this update when it came out as 3.8.14 but had to rollback because of that problem.
I give up. I bought the gold cart, the fedex module, the (apparently deprecated) affiliates module, the UPS module, the drop shop module etc. and it simply was a waste of money.
I gave up on drop shop almost as soon as i tried it because of the instability.
