 * Dear WP gurus!
 * Please help me to clarify:
 * when I’m trying to show posts from a single or multiple categories using this
   in the page code:
 * <?php query_posts(cat=’3′);> or <?php query_posts(cat=’3,4,5′);>
 * as a result I have a completely blank page???
 * But when I excluding the category like this:
 * <?php query_posts(cat=’-4′);>
 * as a result I have all posts except the posts from category with ID 4, as I think
   it works perfect…
    but why then WP generates blank page when I tell him to show
   category with a specified ID??
 * Here is a complete loop code it’s quite simple:
 * <?php query_posts(‘cat=3’) ?>
    <?php if (have_posts()) : ?> <?php while (have_posts()):
   the_post(); ?>
 *  <!–LOOP CONTENT–>
 *  <?php endwhile; ?>
    <?php endif; ?>
 * Thnx in advance for help!
