I need some help to understand what is, or what could be the undefined value that costs 22.7k of Total weight http request in my webpage.

enter image description here

The website is a very basic installation of wordpress in localhost.
Here is the source code from "view source" of the tested page:

What version of Yslow, Firebug, and browser are you using?

themhz commented May 21, 2015

Hello, It is version 3.1.2. on chrome. I assume that it is the font. Because in components tab the same number (22.7k) is listed as font with source http://localhost/wordpress/wp-content/themes/twentyfifteen/genericons/Genericons.eot . Can you confirm?
