Multisite not loading includes, css or js

I am using multisite with subdomains on a server with Plesk 11 installed. I have followed all the steps at Configuring_Wildcard_Subdomains_for_multi_site_under_Plesk_Control_Panel and everything works apart from any includes.

The site is at climaterushdev.co.uk and the subsite at bristol.climaterushdev.co.uk. As you can see main site is ok but sub site isn’t.

I am using the following relative links in the mod_rewrite

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]

As i am on Plesk 11, i don’t have direct access to the httpd.conf so i have to go into /var/www/domain.com/conf and add vhost.conf to add

ServerAlias *.climaterushdev.co.uk
<Directory /var/www/vhosts/climaterushdev.co.uk/>
AllowOverride FileInfo Options
php_admin_flag safe_mode off
</Directory>

I have also added *.climaterushdev.co.uk as a CNAME in the DNS as described in the first article on WordPress re: Configuring Plesk.

I am completely stuck and tried everything i can find. Anybody have any ideas?
