I always separated my new posts in categories like this:
<?php query_posts("category_name=12&orderby=post_date&order=DESC&showposts=5"); ?>
<?php while (have_posts()) : the_post(); ?>
" rel="bookmark"><?php the_title(); ?></br></div>
<?php endwhile; ?></td></tr>
But, it's not working for my new categories as 29, 30 and 31... I think itÂ´s happening since I upgraded my website, and I have no clue of whatÂ´s happening... if I write a category number like 8, it works, if I write a new category number as 31, it doesnÂ´t! :-) And YES, I have posts on them.
