Learn@UW/D2L - Attempt to Take Quiz Results in Blank Page or Internal Server Error

If a student who attempts to a take a quiz receives a blank page or an internal server error message, there are likely duplicate questions in the quiz. Although assigning two questions the same name in a quiz won't create a duplicate question and there is protection against trying to import a question from the question library that's already in the quiz, there may be other ways that a quiz can acquire duplicate questions.

The instructor should be notified to check the quiz and delete any duplicate questions.
