configuring the wp-config.php file

Hi all,

I have included the following into my wp-config.php file at lines 102 and 103 in my localhost :

define( ‘FORCE_SSL_LOGIN’, true );
define( ‘FORCE_SSL_ADMIN’, true);

But since then I am getting these error messages at the login screen for my WP dashboard:

Notice: Constant FORCE_SSL_LOGIN already defined in D:\xampp\htdocs\wordpress01\wp-config.php on line 102

Notice: Constant FORCE_SSL_ADMIN already defined in D:\xampp\htdocs\wordpress01\wp-config.php on line 103

Kindly explain why I am getting these error messages and how I can rectify the situation to force ssl login.

Regards
