Domain mapping error: bad_httpd_conf. Not resolved with previously posted info.

I am trying to map natssweettreats.com to natssweettreats.wpbizsite.com.

I have...
-a dedicated IP on a VPS
-wildcard DNS
-added: define( 'SUNRISE', 'on' ); per instructions
-read all posts that reference bad_httpd_conf
-deleted the following from wp-config.php per recommendation:

--define('DOMAIN_CURRENT_SITE', 'wpbizsite.com');
--define('PATH_CURRENT_SITE', '/');
--define('SITE_ID_CURRENT_SITE', 1);
--define('BLOG_ID_CURRENT_SITE', 1);

-read: http://room329.com/2011/03/12/wordpress-network-on-dreamhost/

and i still get:
"Site Temporarily Unavailable
