Does this plugin hide Media Files, Php Files, PDF Files from users and search engines? How does this plugin prevent search engines from searching these pages? Does it use the default WP Settings > Reading option?

Does this plugin work on a multi-site?

I have created a ‘members only’ page and several sub-pages. I only wish non-users to see the ‘members only’ menu item, not the sub-menus.

Is there a way to hide these?

The documentation says that you can control user access by selecting specific roles for each page, but there are no options displayed in either of the drop-down menus in the setting page. How do I set these?
