Media Pro Skin WWW issue
Design and Skin Customization
This isn't a skin issue, this is because your .htaccess is not setup to redirect the user to your URL WITH www. When anything loads via an AJAX call, the browser checks the originating domain and ensures they match, and "http://www.site.com" and "http://site.com" are seen as 2 different domains to the browser (and for browser security, it will not load content cross domain without proper CORS setup).
The fix is that you need to add some rules to your Jamroom .htaccess file, and based on your post it looks like your Jamroom URL is set to use "www". So that means if anyone requests a URL from your site that does NOT begin with www, the .htaccess rules need to redirect.
So add this to your .htaccess:
# HTTP
RewriteCond %{SERVER_PORT} ^80$
RewriteCond %{HTTP_HOST} ^site\.com [NC]
RewriteRule .? http://www.site.com%{REQUEST_URI} [R=301,L]
# HTTPS
RewriteCond %{SERVER_PORT} ^443$
RewriteCond %{HTTP_HOST} ^site\.com [NC]
RewriteRule .? https://www.site.com%{REQUEST_URI} [R=301,L]Of course replace "site.com" with your domain.
Hope this helps!
