We'll create fresh WordPress site with Private by Default installed. You have 20 minutes to test the plugin after that site we'll be deleted.
When creating new posts or pages (of regular WordPress types or custom post types), this plugin makes them private by default.
Just activate the plugin, no further configuration is necessary (or even possible).
This plugin is a fork of the Private Posts by Default plugin since it didn’t work properly in WordPress 4.3 and wasn’t updated in more than three years.
