the_date not working?

After I installed the new 2.7 version the_date function started to not show on all the posts.

My code:

<?php while (have_posts()) : the_post(); ?>

• “><?php the_date(‘d/m’); ?> • <?php the_title(); ?>

<?php endwhile; ?>

The test site:

Check the “Veja Também” field (bottom) it appears only on the last one.

What’s wrong?

Thanks!
