Hi,

I have just created multisite succssfully but after creating it when I check the new site, I find that the css file is not working properly. That is the look and feel of the website is completly gone.

My .htaccess file is as mentioned below.

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