Why Firebug pretends that my stylesheet is calling my xmlrpc ?

Question

Firebug shows a request which causes a huge delay to http://reboltutorial.com/wp-content/themes/minaflow/none

Details below but I don't understand why it says it comes from xmlrpc and the stylesheet:

Answer 1

1) Please remove SESSION_ID and all cookies from post (it's quote easy for hacker to access to your site with that)

2) In CSS you have 3 times next code:

background: url(none);

That's why it goes to 404 error!
