New Subsite Not Displaying Properly

Hello,

I know this comes up often and have checked the basics. I have created a new subsite before and it displays correctly, now I created one today and the text appears but the formatting does not. I believe my .htaccess, wp-config, and wp-options in the SQL table are all correct but will post them if anyone can see a problem. I am using subdirectories. I think this may be the problem as originally when I set up multisite it wanted to default to subdomains, but I manually changed the subdomain install to false.

.htaccess:

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]

Bottom of wp-config:

// WordPress debugging mode (for developers).
define('WP_DEBUG', false);

define('WP_SITEURL', 'http://my.domain.org');
define('WP_HOME', 'http://my.domain.org');
define('WP_ALLOW_MULTISITE', true);

define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', false);
define('DOMAIN_CURRENT_SITE', 'my.domain.org');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);

In wp_3_options

siteurl: http://my.domain.org/testsite
home:    http://my.domain.org/testsite

Any help is appreciated

PS: This is an intranet site so I am unable to provide links. It is running on a debian vm set up just for WordPress.
