Can’t get the loop to work with WP_Query at all…

Hi everybody,

In index.php I have a column with blog posts and another that is supposed to display the latest post of the type ‘personer’ (Swedish for persons).

This is the code:

<?php $loop = new WP_Query('post_type=personer&posts_per_page=1'); ?>

<?php while ( $loop->have_posts() ) : $loop->the_post(); ?>

	<div class="widget">
		<h3>Person of the month</h3>
		<?php the_post_thumbnail(); ?>
		<?php the_excerpt(); ?>
		<br />
		<a href="<?php the_permalink(); ?>">Read more &raquo;</a>
	</div>

<?php endwhile; ?>

<?php wp_reset_query(); ?>

But this returns nothing. For the previous WP site I worked on I tried to use WP_Query in the main loop (to control number of posts per page until I discovered that you set this up in wp-admin), and it didn’t work then either. What am I doing wrong?
