This plugin creates an additional post status ‘restricted’. This status functions similarly to setting a post, page, or cpt to private. However with this plugin you can specify which roles have access to restricted posts
This is required because natively WordPress follows a publishing/editorial paradigm and therefore the ‘read_private_posts’ capability is only granted to admins and editors.

I have a fresh install with no plugins and Twenty Seventeen and I get this error when I try to activate the plugin: 

The plugin does not have a valid header.

Is this plugin dead?

Unable to Activate

Great plugin, logical interface. But there are two huge downsides:


	No active support from the developers
	It does not work on Gutenberg


So if you're not working with Gutenberg (which will be the default editor in WP 5.0) and you have no need for support: go for it! Great plugin!
In all other cases: find something better, and let me know what you've found, I need a replacement as well ;)
