Hallo!
Found a strange behavior in Odoo shop (2 instances)
When cart is populated with items and customer choose shipping, if the default shipping is canged to secondary, then it's not possible to go to next step as Odoo gives error. If customer reloads page, then it's possible to go further and make a payment. Website address is maana dot lv if anyone can help with this issue.
"Server Error
We are not able to process your payment.
The cart has been updated. Please refresh the page."
