Hi. After i upgrade community quiz to the latest version on today i got the following error on my front end:

Fatal error: Class 'CommunityQuizHelperQuery' not found in /home/xxxxxx/public_html/xxxxxxxx/components/com_communityquiz/models/quizzes.php on line 72

I disabled the component on backend and now i don't get any error.

I use Joomla 3.6.5

Please fix it.

Thanks

Best regards
