I've tried many things ... but I can't list all posts of categories in category.php. Even when I specifying the id directly Wordpress never found my posts ('No post' in the page). However, I can list all my posts and show the category to which they belong.
My code in category.php
<?php get_header(); ?>
<div class="page">
<h1 class="page__title"><?php if (is_category()){
single_cat_title('');
}?></h1>
<?php
$current_cat_id = get_query_var('cat');
$args = array('cat' => $current_cat_id, 'orderby' => 'post_date', 'order' => 'DESC');
query_posts($args);
if (have_posts()) : while (have_posts()) : the_post(); ?>
<h3><?php the_title(); ?></h3>
<?php the_title();?>
<?php endwhile; else: ?>
<?php _e('No post.'); ?>
<?php endif; ?>
</div>
Thanks so much for your help.
