The social media icons do not appear

Sorry for my english :S

Well, the fact is that when I go to customize it section everything is correct, but when I enter the page normally to check any social icon ( I’ve activated them in the right sidebar, header and footer ) does not appear.

Right now I ‘m using a child theme, in the original theme I’ve modified the body’s background in the custom css.

Here are the changes that I have in the child theme

/ * Background * /
body {
background: url ( http://lozzny.com/wp-content/uploads/2013/11/Fondo1.png ) repeat scroll 0 0;
}
# main -wrapper {
background- color: # FAFAFA ;
margin- top: 0px;
margin- bottom: 0px;
}

/ * ————————————— * /

/ * Header * /
header.tc -header {
background : none;
border-bottom : none;
}

/ * ———————————– * /

footer # footer {
border-top : none;
background-color : gray ;
}

footer # footer . colophon {
background-color : gray ;
border-bottom : 15px solid gray ;
border- top: 15px solid gray ;
}

I haven’t changed any other css or php file, just the customize it options and the custom css.

You can see the result here ( the website is in Spanish ) http://www.lozzny.com

What’s the problem?
