Hello guys,
Every time I try to see the Attempts of a Quiz as a teacher or admin I get an error page. The url is: ".../mod/quiz/report.php?id=xx&mode=overview".
Is this a common error? Is there any way to fix it?
Thanks.
ps. I also tried the same thing on another portal with the same Moodle version - and it worked fine. I think it could be some file that I've changed in the first mentioned portal...
