Fatal error: Class 'JComponentRouterBase'

Hello
Couldn't recreate the issue at our end. Can you please share your backend & FTP login credentials via Contact us form, We'll look into it.

Loading Quiz URL presents this message:

Fatal error: Class 'JComponentRouterBase' not found in /home/midlan22/public_html/components/com_vquiz/router.php on line 21

Enabling the Quiz List Layout in Menu item type and selecting the survey causes this error for entire Web site if added to the Main Menu. When added only to the Hidden Menu, the Web site works fine but the error appears once the URL is visited www.midlandmarketingworks.net/index.php/assessment )

Please assist.

Thanks,

Jared
