Thanks for reporting back.
We have taken the following steps to improve MariaDB support:
- Add MariaDB to our CI testing pipeline
- Check for MariaDB 10.2+ (instead of 10.1+) in the Mautic 3 upgrade script
- Check if you’re running a supported database version in the clean installation process
I will go ahead and close this topic now. If you came across any other issues, please feel free to let us know in a new topic
