path-based multi site gives 404 error

Hi,

I’m trying to set up a multi site on the latest word press. When I add a new website, in wordpress it looks okay, but when I visit the site or the wp-admin part of it it gives me a 404 error.

I’ve looked though the support forums here and tried all the solutions people have been suggested, but I’m still not having any luck.

I am running this on the latest debian with apache2.

My .htaccess looks like this:

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# uploaded files
RewriteRule ^([_0-9a-zA-Z-]+/)?files/(.+) wp-includes/ms-files.php?file=$2 [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule  ^[_0-9a-zA-Z-]+/(wp-(content|admin|includes).*) $1 [L]
RewriteRule  ^[_0-9a-zA-Z-]+/(.*\.php)$ $1 [L]
RewriteRule . index.php [L]

The multi site part of my wp-config.php looks like this:

define( 'MULTISITE', true );
define( 'SUBDOMAIN_INSTALL', false );
$base = '/';
define( 'DOMAIN_CURRENT_SITE', 'webbapp.habo.se' );
define( 'PATH_CURRENT_SITE', '/' );
define( 'SITE_ID_CURRENT_SITE', 1 );
define( 'BLOG_ID_CURRENT_SITE', 1 );

mod_rewrite is running according to the <?php phpinfo(); ?>

File rights is 644 and folder rights is 755 as per default. The blogs.dir have the same rights set. Everything is owned by www-data.

Obviosly I must have missed something, but I don’t know what that could be.

Help will be much appreciated! ??

Thanks!
Joakim
