So, I was right about that the database structure and default data is not being installed properly during the SMF setup.

Which MySQL server version are you running? Perhaps SMF doesn't support the MySQL version you are running (too old or too new maybe).

You can use the command below to get the version information or use a tool like phpMyAdmin / Adminer:

Code: (Select All)

mysql --version

Example output:

Code: (Select All)

mysql  Ver 15.1 Distrib 10.1.38-MariaDB, for debian-linux-gnu (x86_64) using readline 5.28

Perhaps also the database engine is not supported.

Look what I found: https://www.simplemachines.org/community...c=560047.0 and https://www.simplemachines.org/community...c=555076.0

You said you were using Debian with quite recent software (kinda). That could mean that your MySQL server is most likely MariaDB instead of the Oracle MySQL server.

Seems like SMF isn't compatible to MariaDB MySQL or your configuration causes some issues. The second topic hints that you might have to change the default MySQL database engine.

Can you post your my.cnf file?
