If a user on our site is logged in and they try to create an order the checkout page just refreshes when they click complete order and no order is created.
If a guest tries to order it works fine.
Is there any noticeable difference in the way the order is processed when a user is logged in?
This started to happen after we upgraded the site to 126.96.36.199 from 1.7
There seems to be 2 relevant errors in the system log:
