Hello, I tried the preliminary update and it did not work. Reverting to the previous version proved quite the headeache..
Since nothing worked on the checkout page I decided to move the entire coupon submitting part to the Cart page. Not an ideal solution but at least adding [and removing(!)] coupons works here.
There is one glitch/misbehaviour in Cart as well, though:
1. When you select one of the free gifts you have to click on “Update cart” only then is the Free gift really selected..
2. If you just select the free gift and go to Checkout, submitting your order in Checkout will show an error “You have to choose your Free gift”..
So, the solution would be: Clicking on a free gift in Cart refreshes the Cart page and adds the gift to your Order.
Is that behaviour possible to invoke?
