Hello,
I have now Moodle 3.9.
I have the same problem as in May [https://moodle.org/mod/forum/discuss.php?d=402704] :
For quiz activities, the grades are not saved, they do not appear in the grade book, and the activity is not completed.
Teachers see student activity in the logs, but not attempts .
Permissions and roles are correct and have not been changed.
Quiz results are not recorded for all students and for all courses.
No error log for the cron, but "cron obsolete" : What does it mean ? can it be related?
what can I do ? where can i look?
Thank you very much if you have any solutions !!
