CaPa Protect is a very useful plugin and I'm very pleased I discovered it. I don't normally write reviews but felt this one was needed. I've been looking for a plugin to hide menu navigation items from both public view as well as subscribers in some cases and this plugin works really well. My use scenario. Contributor role sees a custom menu which is used to develop the site content (assignments, or meeting notes for example). Subscriber role is for paid and trial members and they see everything except the private custom menu. Free visitors also see only what I want them to see. I'm also using a membership plugin called Magic members to further protect content based upon subscriber type (paid, free). The combination of both these plugins helps me achieve exactly what I want with my site and so far no issues on compatibility. If you want to use the site for collaboration within a group without having to use additional passwords then this is the plugin to use. Well done. If it keeps working don't mind making a donation.
