next_posts_link/previous_posts_link return blank!

Hello everyone

I have the following issue with a theme I am developing:

the following piece of code

<?php previous_posts_link(); ?>
<?php next_posts_link(); ?>

does not return any result.

If I use

<?php previous_post_link(); ?>
<?php next_post_link(); ?>

It displays the next post… I’m quite puzzled. Why wouldn’t it work? any suggestion?

The final part of my loop would be like:

<?php endwhile; ?>

<div class="row prevnextsection">
<div class="sixcol"><span class="prev"><a href="#"><?php previous_posts_link(); ?></a></span></div>
<div class="sixcol last"><span class="next"><a href="#"><?php next_posts_link(); ?></a></span></div>
</div>

<?php endif; ?>

heeeelp! 🙂
