Hi everyone,
We are currently running Moodle 2.4. Some of our trainers have recently started using Moodle's feedback file option, which we have enabled for all assessments. However, we are getting reports that feedback files are not saving some of the time.
We have done extensive testing of this issue and the result seems to be that it does work normally, just not all the time. For example, during my testing I was able to send a feedback file to a test student a number of times within the same assessment, but then after a number of tries it just stopped working. The file appears to upload but as soon as the assessment is graded it disappears. To confuse matters further, some of our trainers swear this has occurred after the time an assessment is marked. We have ruled out file type as an issue here - problem occurs independent of file type or size.
Our marking process in pass/fail. We have customised Moodle so that when the pass button is hit, a score of 100% is recorded. When they hit fail, the assessment is reverted to draft and no score is recorded. We noticed that where this issue occurs, a zero grade is somehow recorded in the gradebook instead of no grade. Still doesn't seem like that should matter, so maybe it's just a coincidence.
Our developers have tried debugging this but to no avail. Any suggestions on what to do here, or at least where to look for answers, would be greatly appreciated.
