Hi guys,
I have upgraded to the newest version and I did not receive any errors or whatsoever.
Nevertheless, I have 2 issues:
1. I tried to install the fast checkout extension and got a critical error (see attachment)
2. If I try to make an order as a registered user there are no issues.
However, when I try to make an order as a guest I cannot proceed to the final steps of checkout because I get the following error (see attachment):
Enter your code, hit the "Apply Coupon" button and watch your discount instantly be applied to your order.
There is no coupon for a guest so how on earth do I get this error?
Any ideas and suggestions?
