Learn@UW - Possible Problem in Courses with No Enrollments and Empty Grade Categories
It is possible that you will receive an internal server error (HTML 500) when you select the Grades tool in your course if the following conditions hold:
- There are at least three (3) empty Grade categories in the gradebook.
- There are no students enrolled in the course.
This is a known issue.
If there are no students enrolled in a course, you can resolve the issue by enrolling a student.
