Can't access my login page

Hi all,

I’ve made three major modifications:
-A- WP security>Brute Force>Rename login page: I should access the login page at “mysite.com/?newlogin”,
-B- WP security>Brute Force>Cookie based brute force prevention>secret word + re-direct url: I should access the admin section at “mysite.com/?secretword=1”
-C- WP security>Maintenance>Visitor Lockout: I should have the ability to see the website, whereas the other users/visitors cannot.

My issue is that I can’t access the back-end of my website: neither the login page, neither the admin login section.

When trying to access the new login page I just see the Maintenance page (A et C)
When trying to access the admin section: I’m redirected to the specified re-direct url (B)
