I can not administer my site or a visit or edit anything.
I added only one code is:

function user_role_update ($ user_id, $ new_role) {
         $ site_url = get_bloginfo ('wpurl');
         $ user_info = get_userdata ($ user_id);
         $ to = $ user_info-> user_email;
         $ subject = "Role changed:". $ site_url. "";
         $ message = "Hello". $ user_info-> display_name. "The change in your ranking site". $ Site_url. ", The new rank is." $ new_role;
         wp_mail ($ to, $ subject, $ message);
}
add_action ('set_user_role', 'user_role_update', 10, 2);
