If I go to my Order History page and expand it to show all old orders, normally I can click on an order number and view that order.
However, it appears that if any one or more of the books in that order are no longer offered for sale by Faithlife, and thus their titles appear without a clickable link, then clicking on the order number link at the right to try to view the order page produces a 500: Internal Server Error.
For example, in this excerpt from my Order History, clicking on 5635200 or 5631272 results in a 500: Internal Server Error.


But I can click on 5634484 and it takes me to the order page:

I've spot checked this in a bunch of places, and the pattern appears to hold: whenever any of the books or packages in an order is not available anymore, the order page cannot be viewed. Otherwise it can.
I would still like to be able to see a history of all my orders even if those books are not available anymore!
