Problem with next_post_link on one post

Hi, all.

On my clients site, on one post only, the link to be able to go to the next post doesn’t show up (and, no, it’s not the last post).

This is the post on it’s own page:
https://www.seanborggoesla.com/2009/04/brits-abroad-borg-n-morgan-in-hollywood

This is th code I used to make the “read previous post” and “read next post” there at the bottom (well, the “read next post” isn’t working on this post, which is my problem):

<div class="navigation">
        <div class="alignleft"><?php previous_post_link('&laquo; %link', 'read previous post', 'no') ?></div>
        <div class="alignright"><?php next_post_link('%link &raquo;', 'read next post', 'no') ?> </div>
 <div class="clear"></div>
   </div>

I’ve also noticed that post doesn’t show up if I go to another post and click through using those bottom links. And it seams to skip some others too, I think.

Thanks for any help.
