Hi Ofi
Our config works with all Joomla versions and PHP versions, and worked when we started to work with your templates 2 years ago.
As I did suspected our config does not work cause we do use MariaDB instead MySQL as you can see at the docker sent by RD
We will keep like this, cause the container we do use for MariaDB holds other databases and in terms of management we do not have too many databases engine containers (at least not one for each docker we do develop)
Some years ago we decided to move from MySQL to MariaDB, cause looks faster and more scalable and all the solutions we do have from other providers did the same. So we do prefer to keep MariaDB.
Maybe if you use the standard mode of installation (NOT docker) you will find the same when using MariaDB.
Thanks for your testing and your help on it.
Best Regards
