Show next post and previous post

Try this instead:

<div class="navigation">
   <div class="alignleft"><?php previous_post_link('%link', '&larr; Previous'); ?></div>
   <div class="alignright"><?php next_post_link('%link', 'Next &rarr;'); ?></div>
</div>

You’ll also need to make sure these classes are in your CSS, but that can come later, it’s just aesthetic:

.alignright { float: right; }
.alignleft { float: left }

If that doesn’t work, could you please post a link to your site?

thank you. i was having the same problem. not anymore though ??

@bigrocks – glad to hear it!

Wow, thank you, now it works!!
Is there a way to include the title of the post, for example instead of “next” and “previous”

Yes, I think if you remove , '← Previous' and the equivalent on the Next link, the post title will appear by default. I’ve used this in the past but I find it’s not a great option because post titles – especially those that are longer – can “bump into” each other and/or split onto two lines, which doesn’t look great.

You can see full previous/next options and syntax here:
