Hello here, I had same issue and my coder defined the problem, let me quote him:
“The quiz creation code ( $(‘#wpProQuiz_1’).wpProQuizFront({ … ) is executed before the script (wpProQuiz_front.js) adds that method to jQuery”.
We have made workaround with 1sec. delay for wpProQuiz_front.js but it would be nice to have this solved in proper way (setting the order).
Thank you for this plugin anyway!
