It seems anybody can access to the whole contents of your wordpress website by just typing something at the back of your website address to return to the “404 Not Found” page. This “404 Not Found” page will list down all your pages as well posts. My problem is some of the pages are private and only for certain people to view. With this “404 Not Found” show up, there will be no privacy. As such, I need your help how to overcome this problem.
