No working aymore...

I also have issues with the quiz not playing anymore. I am not sure at which stage it happened. Please check my site at hielspoorinfo.nl/quizzes/hielspoor/doe-d...r-test-5-vragen/play .

In the console I can see an errormessage saying:
jquery.min-29542469.js:2 POST hielspoorinfo.nl/ 500 ()

I tried changing the setting for Jquery on / off as you advised, but this did not solve anything.
Also I disabled my plugin JCH-Optimize, but still no result.
Can you please check?

Did you recently upgrade the vQuiz component? It seems to have caused the issue, Please share your FTP & Backend login credentials via Contact us form along with your order number, We'll look into it.

Firebug does not show anything when we click on the button nor does it show anything when the loader is loading. Sigh.

I noticed that there as an upgrade for Vquiz, so I installed it hoping it would solve things, but now the component is completely screwed up. Both the frontend and the backend (when I check the details for the particular quiz) give me SQL errors:

Error: 1146

Table 'xxxxx.#__vquiz_quiz_score_category' doesn't exist SQL=select score_depend from #__vquiz_quiz_score_category where quizid = 2 order by id asc

Please not that I cannot allow backend and FTP access for security reasons.

Hello,
Please let us know the version you had earlier and the version now you have?

I am not quite sure what the previous version was. I downloaded the zipfile called pkg_vquiz_v_2.3.0.zip last week, as my configuration showed a lower version.

However, in Joomla I have various versions for different Vquiz parts, see attachment


Also when I check the VQuiz component it still shows version 2.1.0, see attachment
