I (or in fact, a tester of dotLRN) came across an error when trying to manage class memberships:
In the ...class-name/members pages (Manage Memberships from class admin page) there is an Admin button for every member of the class. When you push that button, you get the following error:

This applies to every member of every class on our server (w/ PostgreSQL) and with at least two different users with site-wide admin rights trying to get to the page. I couldn't repeat the error on collaboraid's i18n server running oracle.
