Hide backend not working

Hi,

When I tick the “hide backend” option and enter a new slug for the login, for example “testlogin”, it seems that iThemes creates the new login but doesn’t remove the old “wp-login”.
I end up with two login entries, like:
http://mysite.com/wp-login
http://mysite.com/testlogin

… which doesn’t really improve my security!

Anyone know what can be going wrong?

Thanks

Flo
