Students unable to access My Grades, see ‘displayComment’ error

Problem: Students are unable to view the My Grades area when at least one of their grades meets all of the following criteria:

1. Grade/attempt has been marked as “Exempt”.
2. There is no score entered for the grade.
3. A comment/feedback entry has been attached to the grade.

Solution: The simplest workaround for this issue is for the instructor to set a non-null value for all exempt cells (i.e. “0.00”, not “–“). Removing the exemption and/or the comments will also prevent the error from appearing.
