The Restricted Site Access plugin allows you to restrict a whole WordPress site to be visible only to logged-in users. This is very handy for development sites, and for providing members-only sites with no publicly-visible content.
This simple add-on plugin for Restricted Site Access adds a notification icon and message to the admin bar, showing the site’s current restriction status. This notification is only visible to admin-capable users, and means that an admin can always see the site’s current restriction status at a glance.
The plugin shows a locked padlock and a RESTRICTED status message if the Site Visibility setting has been restricted to logged-in or allowed-by-IP users.
It shows an unlocked padlock and an UNRESTRICTED status message for all other settings of Site Visibility.
