In other widget areas SSI will show correctly, but not in header.
This is the code in header.php:
//Get Google Webfont
$pp_font = get_option('pp_font_family');
$pp_font = urlencode($pp_font);
if(!empty($pp_font))
{
wp_enqueue_style('google_fonts', "https://fonts.googleapis.com/css?family=".$pp_font."&subset=latin,cyrillic-ext,greek-ext,cyrillic", false, "", "all");
}
else
{
wp_enqueue_style('google_fonts', get_stylesheet_directory_uri()."/css/gfont.css", false, "", "all");
}
//End Get Google Webfont
