Okey, I solved it by adding the plugin Social login and Members and set the New User Default Role to a role that have no permissions. So now even if users log in to my private pages via Facebook they can not see the pages until I approve them (I get an email from Social login when a new email is added).
But my only problem now is that in the registration page (where I add the code [wp-members page=”register”] there is two links that show when you are logged in:
– Click here to logout.
– Begin using the site.
Is there a way to remove the link Begin using this site? Because I want the registration form to be open for everybody but I have to block that page so not non-members can see my private pages.
