We'll create fresh WordPress site with Redirect anonymous users installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Users who are not logged-in will be 302
redirected to an absolute URL specified by the admin.
Any user who can log in, from admins to subscribers, will be able to access the site.
To turn off this redirection, clear the redirect URL field, or simply disable this plugin.
This is a very minimal plugin for very simple use cases, when you want to avoid the bloat of a full-on redirection plugin.
