All the button dont work anymore

Hi,
It doesn't seem to be an issue with the language. Please share your backend & FTP login credentials via Contact us form, We'll look into it.

Hi, we have installed the vquiz and it was working fine. We did some ajustement to have it work for us and we installed the french file to have some quizzes in french. Now we can see the first question, all the buttons but if we press next or previous (in the french version) suivant ou précédent, nothing is working. Someone has a suggestion of why it stopped ?

Thanks again.
