Hello support, I have a license and a working site running Joomla 3.10, PHP 8.2, MySQL 5.7, ARI Quiz 3.10.21.
My goal is to upgrade the site to Joomla 5.4, PHP 8.4, MySQL 8.0, and ARI Quiz 3.10.21.
Since I couldn't find an answer on the support site: www.ari-soft.com/docs/ariquiz/html/ARI_Quiz_UserGuide.html
Please answer: ARI Quiz 3.10.21 will work on Joomla 3.10, PHP 8.2, and MySQL 8.0.

Hello,

"ARI Quiz" v. 3.10.21 is compatible with Joomla! 3-5 and works with MySQL 8.x and PHP 8.x.

Regards,
ARI Soft

Hello support, thanks for the reply. I have another question. A new installation of ARI Quiz 3.10.21 fails in the Joomla 5.4 admin panel, returning a Bad Gateway 502 error. However, ARI Quiz 3.10.21 is installed in the control panel. Clicking the link returns a Bad Gateway 502 error.
Help me figure out what's wrong?

Hello, ARI Soft support team.
I've tried this on other sites (Joomla 3, Joomla 4, and Joomla 5), ​​and the issue is the same.
As per your request, I've sent you access to the test site's admin panel to your email address.

Hello, support team! I'm waiting for a response. To resolve my issue, an account on the Joomla 5.4 test site has been created for you at your request and sent to your email address. Did you gain access?
