Forum .LRN Q&A: Re: dotLRN class attendance

Thank you very much. I was able to install dotlrn-attendance, add the applet to a class, and add an event, or session.

But, when I click the "attendance" link:
http://localhost/dotlrn/classes/dep01/dep01.sub01/class01/attendance/admin/mark?item_id=3427&return_url=/dotlrn/classes/dep01/dep01.sub01/class01/one-community-admin?

I received the server error below. It looks like I am missing another applett that has additional user info?

Database operation "0or1row" failed (exception NSDB, "Query was not a statement returning rows.")
