Quiz Stats: 500 Error

This is a known issue in D2L. While we're not sure when Desire2Learn will fix the bug, it's helpful to know how to fix the cause of the error!

Problem description: Instructor receives a 500 Error when attempting to view statistics for a Quiz.

Solution: Check to see whether any student has a quiz attempt that is ungraded.

An ungraded Quiz will cause the 500 Error because D2L cannot calculate statistics when any attempt has a "null" score -- an absence of a grade. (The null score can be caused by an interruption occurring while a quiz is being submitted, for example, losing network connectivity. )

To grade the ungraded Quiz attempt, follow these steps:
  1. Click on the "Grade Quiz" icon.
  2. Click on the Attempt for the student whose quiz was not graded.
  3. Click the "Auto-Grade" button.
  4. Click Save.
Quiz Stats should now be available without the 500 Error.
