If I try to add a super admin using "Admin List/New Admin" I get this:

PHP Fatal error: In read_string: expected config min_password_length to be a string, but received a integer in /var/www/postfixadmin-3.3.13/model/Config.php on line 75

If I go back into setup and try to add the same user, it seems to do nothing.

Everything was newly installed today on an AWS instance. Ubuntu 22 / MariaDB / etc. PostfixAdmin DB seems to be working fine so far other than this issue. (I can login fine, create/delete records/etc)

The only old portions of this server are the imported database and config.local.php (with minor changes for db connection-nothing really added to it). The old server the database/config came from are running new postfixadmin, but I had not added an admin to it in a long time so do not know if it's broken on it, too. This feels like a new issue, though. And as you can see, 'setup screen' checks out okay, as far as that goes.

If you need more info let me know.
