Hey Klemen, I would like to be able to define a custom ‘Service Message’ for the maintenance mode. Ideally, when creating a service message, I could specify that it should be displayed on the ‘Maintenance mode’ page. Thank you very much! Keep up the wonderful work, I just love HESK! ) Best regards! Stefan.

That's not optimal because during the maintenance mode, changes may also be made to the database.

Instead, I recommend that you change the maintenance message text using custom-text.php
