Quiz Stuck Loading after Answering Question

I have just started creating my first quiz. I'm testing it live on a hidden page of my site (public, but not accessible to anyone who doesn't know the URL). I have three questions created but when I click next after answering the first question, the loading bar pops up and the next question never loads. Is this a bug or am I doing something wrong on my end?

Hello,
Please try turning off Lad jQuery library option in vQuiz configuration in backend. And If it doesn't work, disable error reporting in global configuration. If you still find the issue, please share your backend & FTP login credentials via Contact us form. We'll look into it.

Hi Daniel,

The Load jQuery option was already set to "No" and error reporting set to "None." I will share FTP credentials via the contact us form today.

Hi,
The issue is resolved on your site, please check...
