I'm running Moodle 1.9 (The exact version it gives me is Moodle 1.9.9+ (Build: 20100707)) for a business' training department.
We had a teacher show us two grade reports. One showed completed assignments, and the other showed missing assignments. I verified that the grades were missing, and we're hesitant to restore from a backup until we know the root cause of this.
Does anyone have any idea what went wrong?
