The ability to determine whether a reservation made for today can be placed through the website has been moved from the organizational settings to the type.
This makes it possible to determine for each type whether reservations can be accepted for today. This can be used for example when you want to make this distinction for camping and holiday homes.
For this to change, you can edit any type. When you create a new type the settings are adopted form the most recently added type.
