Restart Course trigger button shows blank screen
I'm having issues with an assessment course I'm developing. There are 25 questions and the user needs to get 100% to pass.
If the user gets a question wrong, a warning automatically displays informing them they need 100% in order to pass. In that warning box, the user can select to continue (just to practice) or restart. I made the restart button trigger Restart Course, and in the player template I set the course to Never Resume.
The problem is when I test the course and click to restart, a blank grey page appears (screenshot attached). Help! I've tried Reset Results, same thing happens. Don't know what else I can do.
