is-current class not applying to single WordPress post

[Josh Johnson]

If you go to http://dev.joshuajohnson.co.uk/ – the “is-current” class is added to the respective pages <li>. On a single post however the class is not added.

Any ideas why this is happening?

Solved using this function:

function my_special_nav_class( $classes, $item ){
 if( is_single() && $item->title == 'Blog' )
    {
        $classes[] = 'is-current';
    }
    return $classes;
}
add_filter( 'nav_menu_css_class', 'my_special_nav_class', 10, 2 );
