Quiz doesn't show

Hi there,

The plugin really looks great and handy, thanks for that!
Unfortunately I can’t get the quiz start. When I enter de shortcode on a page [WpProQuiz X], it only shows this in text, you don’t see the quiz. When i edit de quiz and press ‘example’ it works perfectly. How can I fix this? I already tried this: [raw][WpProQuiz X][/raw] , but it doesn’t help.

Hope to hear from you soon! Thanks a lot in advance.

Greetings, Vera
