Continue button not working

Hi:

I'm delighted with my vQuiz and with the custom work you did for me. I'm having a little issue with the continue button. There have been many updates after the last version.

Since you did custom work for me with the results module. I was always afraid of updating not to lose my changes. I'm still working on version 2.5.11. Can you help to that version and still maintain the changes you made for me?

I'm sending you the login credentials through the contact form, for you to check that for me if you please.

In the new version 2.5.20, there are plugins for community builder that I use; I would be interested in knowing how that works. I was looking for your changelog of the extension, but I couldn't find it.

Can you send me the info to know what's new in vQuiz?

Thank you in advance
