I have a school where they are just starting to use the manual grading system (to grade normal school activities). Teachers have set up categories and items, but now, after they input the grades and try to save them, they get the following error:
You don't have permission to access /grade/report/grader/index.php on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
Just to be sure, I completely reinstalled Moodle, but the same problem appeared. I also turned on debugging, but after I click on the Update button, the aforementioned error page is displayed.
Then I recreated the same essential course environment (separate groups, with groups and groupings) with a couple of students. This was done on another installation (same Moodle version) under the same site; here I didn't have any problems when saving the grades.
So, I backed up the course from the first installation and restored it on the second one. I got the same error.
Finally I restored the course on my local installation (same Moodle version), and here I was able to save the grades.
Thanks in advance for any help, it will be truly appreciated.
