We have an issue with uploaded files disappearing from assignments and the grade book.
Using the Upload a single assignment option, a student has uploaded a file, the teacher has graded the work and commented on it, but then the file has disappeared from view. The student has tried to re-upload the file, but this hasn't solved the problem. The file(s) are in the moddata folder.
There are over 600 students on the course and 12 teachers. At the moment only one teacher has reported a problem, which is affecting several of her students and on several different assignments. But the majority of her students don't appear to be affected. I suspect the problem may be affecting other students but their teachers haven't realised yet.
We are using Moodle 1.9.5, mysql 5.1.33 and php 5.2.9.2
Has anyone experienced this problem?
Any help gratefully recieved
Thank you
Barbara
