Alex:
Thank you for replying so quickly!
It didn’t work for me in the beginning, and the reason was that the quiz results only appear for published posts. If you try to save a draft with a shortcode [QTL-Quiz id=1] and click preview, the test(s) will show, but not the results. I end up showing my home page with the url https://abc/?action=markTest
. Display feedback is turned on for the quiz.
If you try the same thing for an individual test with a shortcode [QTL-Question id=1], the preview works fine and the results will show as well.
Another thing I noticed – for quizzes drop down shows 0 as available selection from the drop down for the pot. I wonder how zero can be used?
