Install problem !

Hey !

I've just installed domain-mapping plugin but it doesn't work :s !

As mentionned in the install process, I've put "domain-mapping.php" in the "mu-plugins" folder and "sunrise.php" in the "wp-content" folder. In "wp-config.php", I've added the good line :

define('WP_DEBUG', false); 

/* Domain Mapping */
define ( 'SUNRISE', 'on');

/* Autoriser le Multisite */
define('WP_ALLOW_MULTISITE', true);

define( 'MULTISITE', true );
define( 'SUBDOMAIN_INSTALL', false );
$base = '/gites/';
define( 'DOMAIN_CURRENT_SITE', '' );
define( 'PATH_CURRENT_SITE', '/gites/' );
define( 'SITE_ID_CURRENT_SITE', 1 );
define( 'BLOG_ID_CURRENT_SITE', 1 );

After that, nothing related to domain-mapping appeared in "settings->settings"... So I can do nothing !

I use Pro sites too and a lot of other WPMU dev plugins.
