When I edit grade in the grader report, and hit submit to update the grade, I get this error: A misconfiguration on the server caused a hiccup. Check the server logs, fix the problem, then try again. URL: http://www.drmitsch.com/onlinelearning/prc2010/grade/report/grader/index.php Anyone have any idea how to fix this problem? I've tried to reduce the number of students I display, but I'm running out of ideas about how to address this, and the semester's end is approaching. Thanks for the help!
