In one of my curses I have three quizzes, in the start of the week I had the problem described here:
https://moodle.org/mod/forum/discuss.php?d=173464
I have manually made the changes in the report.php file and at least it started to show the grades and the "Overall average" inside: quizzes->results
But I still can't see the "Overall average (Submissions)" in the "Grades->Grader Report" for all quizzes, it seems it is not pulling the results.
One of the quizzes it shows but the other two doesn't.
Do you have any clues what is going on?
Moodle version: 1.9.7 (Build: 20091126) - not possible to upgrade, but I can make changes in the files as necessary
