Note: Assuming that it’s WP single site and Apache server. Your site’s htaccess file should be writable. After applying above settings the backend login URL will be http://www.YourDomain.com/wp-login.php?hide_my_wp=1234 (you can change secret code “hide_my_wp=1234” from general settings tab)
Looking at your site’s page source it seems like default WP paths are not being replaced at all. Can you please let us know your website’s wp-admin login details (as private reply), so that we can look into the issue further.
