Via the portal administration settings settings of the individual portal interfaces can be changed. After a click on the desired portal in the list, the settings are displayed in the lower area. The “advanced settings” are explained here .
When you deactivate a portal interface, no real estate is deleted from the portal. If there are still properties published in the portal, the status of these will be reset and a reactivation of the interface will not restore them.
Portals can be deleted from the list and then reappear in the list of available portals.
Note, changes of the access data can also be changed for groups – Actions bar – “Group portal settings”
