Besides the exception, the argument position should also be fixed (required arguments shouldn't appear after optional ones).

In order to simulate it in OJS 3.4, it's needed to add a feature flag on the config.inc.php and also run a migration.

To Reproduce

1. Access the Administration > Site Settings
2. See error
