I have created content using the Personality Quiz. The activity runs fine on H5P.org and it also renders in Moodle when I am building the course (I use the Chrome browser for development).
When I attempt to load the content in a course (in Firefox) under Guest access, the module doesn't appear. The description displays, but there is nothing after that. I turned on Firebug and two errors appear in the console:
Unable to find constructor for: H5P.PersonalityQuiz 1.0
TypeError: instance is undefined
