Last night I upgraded our site to build 11129.  This morning, a user reported not being able to submit a ticket for approval.  On his end, when he clicks the "Submit for Approval" link it opens the popup but it's blank.  When I do it (as the admin), the popup shows the "To" field and the word "Subject" but then it just says "Sorry an error has occurred."

When I first got the site running, I saw the error about backup credentials needing to be updated, which I did.  Now I'm wondering if there is some other setting that needs to be updated.
