When I create a quiz I cannot see the questions - I get a blank page. However, I can preview the quiz (have seen this problem in the forums, but can't find a resolution)
If I change the URL from //...moodle/mod/quiz/view.php?id=4 to //...moodle/mod/quiz/attempt.php?id=4, then I can view the questions successfully.
When I turn bugging on, I get the following error when I click on a quiz:
