Every subdomain redirects to primary.

So, here’s the deal.

I got one WP Multisite installed with 1 subsite. Im running the whole thing in subdomain “mode”. I did the whole DNS-pointer (A *.domain.se) to the correct IP.

Now the problem, even though i created a subsite in wp-admin (lets call it foobar), when i type in foobar.domain.se i get redirected to the mainsite. foobar.domain.se/wp-admin/ gives a 404 error.

Is it host related or something wrong in my config? More info, it got a shared IP – might be the problem (even though I got the impression it should work anyways)? Iäve searched like crazy on the web, in my htaccess and for hostsettings – and it should be the correct ones.

.htaccess
# BEGIN WordPress
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]

# uploaded files
RewriteRule ^files/(.+) wp-includes/ms-files.php?file=$1 [L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ – [L]
RewriteRule . index.php [L]
# END WordPress

wp-config.php

define(‘WP_ALLOW_MULTISITE’, true);
define( ‘MULTISITE’, true );
define( ‘SUBDOMAIN_INSTALL’, true );
$base = ‘/’;
define( ‘DOMAIN_CURRENT_SITE’, ‘xn--vrnamo-bua.nu’ );
define( ‘PATH_CURRENT_SITE’, ‘/’ );
define( ‘SITE_ID_CURRENT_SITE’, 1 );
define( ‘BLOG_ID_CURRENT_SITE’, 1 );
define(‘SUNRISE’, ‘on’);

Thanks.
