Learnpress quiz won't start

First time using Learnpress. Set up first course, lesson, quiz & questions. When I view the quiz, I can see the question titles, but no answer options. When I click on “Start Quiz” nothing happens. Is there some setting I’m not finding to turn this on or something?

I read somewhere this could be incompatibility with the theme. I’m using Nirvana. I also read someone saying something about PHP version incompatibility. I tried changing it somewhere in my host admin account from 4 to 5 and it didn’t make any difference. (Not sure if that’s where I was supposed to alter than or not.)
