Subsite stoped working

So today my subsite stoped working :slight_frown:

First, my setup is like this:


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

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

# add a trailing slash to /wp-admin
RewriteRule ^wp-admin$ wp-admin/ [R=301,L]

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

# END WordPress

and i got this in the wp config:

define( 'WP_ALLOW_MULTISITE', true );

define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', true);
define('DOMAIN_CURRENT_SITE', '');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);

so i am running a mu with subdomains, and i have setup a wildcard in cpaneld *

i have several subsites setup in wordpress and, but suddenly they all stoped working.
going to any of the subsites created in wordpress just redirects to the main wordpress site.

any other subdomains, out side of the wordpress install, works just fine.

My wordpress install has been working fin up until now :disappointed:

Any suggestions on how to fix this?
