I have 3 moodle instances on the same server running the same version. Since I upgraded to 3.6.2, 1 of them is having issues converting student submission (docx) documents to pdf's for annotated grading.
My tests that I've run produce non-consistent results:
I will refer to instances as instance a, b, and c – where c is our most active
Test 1:
Newly created Docx files in Word 2013
a) Instance a - Existing course/assignment - edited submission, uploaded new doc, went into grading and pdf was generated.
b) Instance b - Existing course/assignment - edited submission, uploaded new doc, went into grading and pdf was generated.
c) Instance c - Existing course/assignment - edited submission, uploaded new doc, went into grading and pdf was generated.
Test 2:
Downloaded submitted doc from student submission on instance c that is not generating pdf
a) Instance a - Existing course/assignment - edited submission, uploaded new doc, went into grading and pdf was generated.
b) Instance b - Existing course/assignment - edited submission, uploaded new doc, went into grading and pdf was generated.
c) Instance c - Existing course/assignment - edited submission, uploaded new doc, went into grading and pdf was blank
Test 3:
Used same doc from test 2, but open and saved as a new document with a new filename
Stopped testing a and b as it doesn't seem to be an issue
Instance c - Existing course/assignment - edited submission, uploaded new doc, went into grading and pdf generated as expected
Test 4:
Went into an existing course/assignment where issues was reported to me. First assignment - grade - went through all assignments and pdf was generated from docx submissions for all students.
2nd assignment - no submitted documents are being generated.
Once in awhile this error appears in my log:
PHP Warning: touch(): Utime failed: Permission denied in ../moodle/files/converter/unoconv/classes/converter.php on line 139
Does anyone have any ideas as to what the issue might be?
