Hello,

I have cjlib 4.1 and cq 7.4.3 installed and I only see empty pages in the backend.

Access your database and delete the CQ menu items by executing the following query
delete from xxx_menu where link like ‘%com_communityquiz%’;
replace xxx with your table prefix
Go to Menu Manager->Menus in your administration site and click on Rebuild button on toolbar
Now install the component again

I followed the instructions but there was no improvement.

What can I do?

Joomla 6.0
PHP 8.4.14
Database 10.11.14-MariaDB-deb12
