I keep getting the same "Loading" screen when trying to log into the assignments and quizzes for one specific course. It doesn't happen for other courses I teach, and it also doesn't happen for another instructor who tried going into the same course.
I can access the assignment via email when I get the notification that a student has finished an assignment, but it doesn't take me to the same SpeedGrader screen that I normally would grade assignments in. Instead, it takes me to a "Submission Details" page. So I can still input grades, but it's not letting me access the SpeedGrader I normally use.
