I backed up/restored courses into a new Moodle. Now students can not view assignments (teachers were having issues viewing assignments as well). I don't think it has to do with backup/restore because I created a brand new course, used a newly created user and added a new upload an assignment. I am still getting an error message when clicking on the assignment link as a student: "Sorry, but you do not currently have permissions to do that (View assignment) More information about this error :"
