Recently, I am having a few faculty notice that the grades and feedback is missing for particular students. The symptoms:
- The rest of the student grades seems fine.
- For the students that are missing the grades, most of the grades (approximately 80%) are missing while a few grades for a couple assignments show up.
- Another weird thing is that for the student having the problem, the greadebook report shows up all incorrectly formatted for some courses not even listing all the assignments. While for other courses the grade report shows up fine but with missing grades.
- LAMP setup running on Ubuntu.
- Moodle 2.3.1+ build 20120712
What might be causing such inconsistencies and how can I get the grades back for these students and fix this problem?
