We upgraded from 2.9.1 to 3.5.3.
we can make a quiz but when i click "edit quiz" and attempt to show the question bank the browser just freezes when trying to load the question bank. i have made the questions in the bank and then trying to add them to the quiz. However the screen just sits there as if it is frozen. You have to close the browser and reopen it to try again but it continues to happen.
I made a quiz in another course and added questions from the bank. However in that course, I only had a few questions in the bank rather than a lot . These other classes have a large number of questions in their categories within their question bank and the bank is not loading.
I turned on debugging but it won't show any errors since the screen just freezes. I have tried this in both firefox and chrome with no success.
Please help.
Thank you
