• In viewing or grading the assignment of students, the progress wheel just keeps spinning and I cannot see the submission.

Solution: press “Change user” option (upper right) and reload. See illustration below. (The viewer could just be stuck with a document for which Moodle doesn't have the right viewer. Pdf files should work just fine. Your browser should also display such document type.) Cycle through such “Change user” option, especially if initially the pdf document doesn't load immediately.

• Viewing <url>/my outputs this error message:

Coding error detected, it must be fixed by a programmer: assign_print_overview() can not be used any more and is obsolete.

We have no solution at the moment. But the right panel already displays a user's courses.

Clicking on your profile picture (upper right) also gives you direct access to your personal profile under which all your courses are listed.
