It looks as though you have some broken links on your website pages.

By fixing the URL of these links, the line-through should disappear.

If the links aren’t broken, then verify the source of your page, and remove the class “broken_link” on all of your anchors, like so:

Before:

<a class="broken_link" href=""></a>

After:

<a href=""></a>

The below code should only output the parent category once.

<?php the_category( '&bull;', $parents, $post_id ); ?>

I’m not sure if this would fix your issue or not, but I’ve noticed on line 25 of your no-sidebar.css file the there’s a typo:

max-width: 980pxpx;

you should put ‘980px’ instead of ‘980pxpx’

Have you tried this?

<?php echo get_category_parents( $cat, true, ' &raquo; ' ); ?>

Which theme are you using?
