We are running Moodle 2.5.5 on mySQL and ubuntu/apache. Moodle has been up and running for most of the year. We are using external enrollment from a mySQL table. The table has the course short name, user name (AD user name), and role. Up until today we had not experienced issues. The import failed today on students and no students had any courses. We re-ran the import and everyone was put back into their course. Unfortunately, none of the students have grades on the grader report. When I look at the assignments, grades show up. If I re-grade an assignment it shows up on the grader report. Manually enrolled students are showing up fine.
When I look at the assignment for a recent course students are showing up with "No submission" but also showing up as "Graded". When I update the grade I can see feedback comments and see that there is a grade there. The last modified date is almost a week ago.
Is there anything we can do to get the grades to show up properly? I have done several searched and saw some options for students who are manually enrolled to have their grades recovered. Does this sound like the same kind of issue?
