I am running Moodle 2.6 and I have a problem with reviewing an attempt on a quiz.
The attempt for one student is showing as finished and the tutor got an email with the link, but the link does not work and when I try to access the attempt through grades it just opens a blank page.
I have turned on debugging for developers and there is no error message.
Grateful for some help.
To options to explain this:
I have checked the permissions for the user and there does not appear to be anything wrong.
By blank screen I mean totally blank, all I get is a white page, so its not like the review opens but there are no answers, I am just presented with a white page.
Oh, I see. In that case an error is happening. Turn on Debugging, and you should get an error message that gives more information.
The error message i get is:
Fatal error: Out of memory (allocated 75497472) (tried to allocate 6848434 bytes) in /homepages/9/d517133489/htdocs/clickandbuilds/Moodle/WCSMMoodle/cache/classes/helper.php on line 535
That is not a helpful error. Obviously somethign about that attempt uses more memory than the others, but the error message does not give us much clue about what that is.
If you want to try to debug this further, you would probably need to do something like run this query https://docs.moodle.org/dev/Overview_of_the_Moodle_question_engine#Detailed_data_about_an_attempt for the attempt in question.
Or, you could try telling us which version of Moodle you are using, and which question types are used in that quiz.
