drashok on "[Plugin: WordPress SEO by Yoast] breadcrumbs not showing up"

Hi,

I am using updated WordPress and wordpress SEO plugin.

I inserted the script given in the plugin for breadcrumbs just above
<?php while ( have_posts() ) : the_post(); ?>
in single.php.

The breadcrumbs is not showing up.

What do I need to check or do differently?

Thanks in advance,
Ashok Koparday
