When trying to add multiple questions on a quiz, I get an empty screen (see screenshot).
Purgin all caches fixes the problem, but the problem occurs again after adding one question, so it's not very feasible to that for every question.
This happened to me on Moodle 2.4.0, and also in 2.4.1 after upgrade. I don't use any custom plugin nor nothing strange.
Does anynone have a clue on how to fix that? Does anybody know where the Moodle cache is?
