After upgrading to 1.2.4 I have been getting an error of “Order No Longer Exists” when clicking to view the details of certain orders during the 1 month period prior to the upgrade. I can view new orders and older orders without a problem and the affected orders even display the customer name and item in the order list (I just can’t see any more details or update the order status).
