I am designing my wordpress website and I want nobody should know that I am using wordpress for my site. I designed my custom login page with custom URL and managed my logged in users to get HTTP 404 error if they try to access wp-admin or wp-login but only thing left is that if a guest who is not logged in try to access wp admin by simply typing http://www.mydomain/wp-admin on browser gets wordpress error which reveals everything. So I need a code so those guests also get HTTP 404 error. They should be redirected 404 page only because I set a ban for those users who get more than 5 HTTP error. Anyone please help.
