No working aymore...

Hello,
Thanks for the info. There are two way to resolve the issue:

1. Provide us backend & FTP login credentials, we'll correct the issue, vQuiz would also be upgraded.
2. We'll send you the previous version you can reinstall it, the issues will be resolved but the version would remain 2.1.0

Please let us know your thoughts....

Please send me the downgrade then as my security policy is not to allow backend access. Note that already before the upgrade things were not working, so not sure if this will solve this.

Ok, I received the upgrade and things are working again. Thanks for that.
However, the fact that I cannot upgrade to the latest version is not really the way to go. I hope a really stable version can be released soon so that I can stay up to date with updates.

HELLO,
it seems that I have the same problem.
When I try to create a new quiz I get the error:
1146 Table 'pharma1_17jagd.#__vquiz_quiz_score_category' doesn't exist SQL=select * from #__vquiz_quiz_score_category where quizid=0

Also when I try to open my "old" Quizes from the frontend I get the error:
1146 Table 'pharma1_17jagd.#__vquiz_quiz_score_category' doesn't exist SQL=select score_depend from #__vquiz_quiz_score_category where quizid = 39 order by id asc
1146 Table 'pharma1_17jagd.#__vquiz_quiz_score_category' doesn't exist SQL=select score_depend from #__vquiz_quiz_score_category where quizid = 40 order by id asc

I think you should test your update Versions first before the user gets it.
I do not provide you with backend & FTP login credentials because it is a site with more than 3.000 Artikels and I spend a lot of time.
Please let me know what I have to do that I get 2.3 running.
I use joomla 3.5.1

Hello,
Please let us know the version you had previously installed. We haven't released the upgrade package yet and you upgraded it with the new version.

I used 2.2.3
