Hello,

Just install this software http://poedit.net/wordpress on your computer. Then run it http://screencast.com/t/wv1A4XtTKbz and import en_US po file from your theme folder/languages into the program.

Next translate your labels like in the screenshot http://screencast.com/t/LhyzzhLJMda and check your site again.

If your site admin is in another language (other than English) then click here to create new po file http://screencast.com/t/gliXcWMMoHuy for your language.

Import en_US file from theme folder/language http://screencast.com/t/GTU9BisAcIw and select your new language from the Translation Language dropdown menu http://screencast.com/t/tBz2EbaA64fA and translate like advised previously.

When you've finished translating, upload your new .po files to languages folder on your live server.

If you don't want to loose changes after theme update, install and activate child theme. Then inside child theme create folder language and copy your translation files there. At last paste this function into child theme functions.php file
if(!function_exists('eltd_load_child_theme_domain')) {
    function eltd_load_child_theme_domain() {
        load_theme_textdomain('eltd', get_stylesheet_directory().'/languages');
    }
    add_action('after_setup_theme', 'eltd_load_child_theme_domain');
}

Thanks
