404 error on multisite

Hello world !

I read topics and topics since yesterday and I don’t find the solution to my problem…

I trying to migrate a multisite wordpress from localhost to my server. All works perfectly on localhost but on my server I can access to the site and administrate all sites but when I want to access the second site I have a beautifull 404 error from apache. I’ve installed multisite into subfolder mode.

Here is my .htaccess :

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [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).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]
</IfModule>

And here is my wp-config.php :

/* Multisite */
define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', false);
$base = '/';
define('DOMAIN_CURRENT_SITE', 'sub.domain.com');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);

And my virtualhost :

<VirtualHost *:80>
        ServerAdmin webmaster@localhost
        ServerName sub.domain.com

        SuexecUserGroup my_user my_user

        DocumentRoot /home/my_user/public_html
        <Directory />
                Options FollowSymLinks
                AllowOverride All
        </Directory>
        <Directory /home/my_user/public_html/>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride All
                Order allow,deny
                allow from all
        </Directory>

        ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
        <Directory "/usr/lib/cgi-bin">
                AllowOverride All
                Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
                Order allow,deny
                Allow from all
        </Directory>

        ErrorLog /error.log

        # Possible values include: debug, info, notice, warn, error, crit,
        # alert, emerg.
        LogLevel warn

        CustomLog /access.log combined
</VirtualHost>

My server is under Apache/2.2.22 (Debian), PHP 5.4.35.

I think I missed a configuration somewhere on the server or missed something on my .htaccess but I d’ont found what…

Any ideas ?

Thanks for your help 😉
