Subdomain multi user setup not working

Hi,

I want to install WordPress 3.0 from scratch, then create a network.

I followed all the steps outlined here: http://codex.wordpress.org/Create_A_Network

1) I installed WordPress 3.0 from scratch in the root folder of example.com.

2) I edited the wp-config.php to allow the multisite feature.

3) I installed the network inside the Wp admin, I chose subdomain setup.

4) I added the wildcard DNS in cpanel: I added this subdomain: *.example.com.

5) I created the blogs.dir directory under /wp-content/, thend added the required lines into wp-config.php and .htaccess.

Now I go to Super Admin -> Sites -> Add new -> something.example.com.

But after that if I go to something.example.com, I see only the default cpanel welcome page. something.example.com/wp-admin triggers 404 error.

What am I doing wrong?

Here is my example.com/.htaccess file:

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]

I added this into example.com/wp-config.php:

define( 'MULTISITE', true );
define( 'SUBDOMAIN_INSTALL', true );
$base = '/';
define( 'DOMAIN_CURRENT_SITE', 'example.com' );
define( 'PATH_CURRENT_SITE', '/' );
define( 'SITE_ID_CURRENT_SITE', 1 );
define( 'BLOG_ID_CURRENT_SITE', 1 );

In cpanel, in the subdomains area, I can see the *.example.com subdomain in the list, the document root of *.example.com is /public_html.

If I go to anything.example.com, I always see the cpanel default page created by Hostgator (a welcome page), and in the address bar of the browser, I see the anything.example.com domain.

The wordpress blog on http://www.example.com works fine.

If I remove the *.example.com subdomain, then I get 404 error if I go to anything.example.com.
