Comment 1 for bug 1175711

I confirm that at 2.4.2 the internal server error occurs when trying to renew an item that is bookable or has a booking reservation on it. Steps I took:

1. Set up an item to be bookable and created a reservation for it in the future (far enough that the time of the reservation wouldn't be overlapping with the checkout and renewal dates).

2. Checked the item out to my account on the training system.

3. Was able to renew the item in the staff client with no issue.

4. In the TPAC, even though it says I have 1 renewal left for the item, when I try to renew, it gives the 500 Internal Server Error.

I can renew other items on my account via TPAC with no issues.
