remi5737 on "[Plugin: Jetpack by WordPress.com] wordpress-post-widget.php misses echo $args['after_widget'] invalidating html"

Jetpack_Display_Posts_Widget:widget does NOT correctly close the widget html.

It does contain

echo $args['before_widget'];

but not

echo $args['after_widget'];

I fixed it by adding below code on line 108

old

echo "</div>";
    }

new

echo "</div>";

        // revhack, 24-12-2013 12:27:02
        echo $args['after_widget'] ;
    }
