Yesterday a customer called us regarding she could not place an order, but actually, the order has been placed and she was directed to the Review Order page with an error message
"We can't place the order".
I checked the log file and found it is due to her billing address record in
qoute_address does not have "customer_id" value so it could not pass the validate function in
However, she did place the order as a registered customer and her shipping address record has customer_id.
When I checked the similar cases, I only found one happened last Oct. So it rarely happens and I even cannot repeat it.
Does anyone was faced with the same issue before or know where is the problem?
