Apply for changing vQuiz domain

I developed the vQuiz on a development server but when I migrate the quiz from the development server to production server, it seems the vquiz do not work anymore (clicking continue with no response). Is it about one domain issue? If yes, may I just apply to change the vQuiz domain, please?

Hello,
No, It's not a one domain issue. Seems to be a Javascript conflict. Please share your backend & FTP login credentials via Contact us page, We'll look into it.

Hello,

I do not have FTP login but still can provide the Super User access of Joomla backend, does it help for the investigation?

Best regards,

Cyris
