title: wordpress - category__not_in not working
body: <p>I'm having a problem getting my query function. I need to run the loop, excluding a particular category.</p>
  
  <p>I'm trying to use <code>category__not_in</code>, but is not working at all some.</p>
  
  <pre><code>&lt;?php
    $args = array(
      'post_type' =&gt; 'post',
      'post_status' =&gt; 'publish',
      'category__not_in' =&gt; array( '44' ),
      'posts_per_page' =&gt; 9,
      'paged' =&gt; get_query_var('paged')
    );
    $query = new WP_Query( $args );
  
    query_posts($query);
  ?&gt;
  </code></pre>
  
  <p>I've already tried:</p>
  
  <pre><code>'category__not_in' =&gt; array( '44' ),
  'category__not_in' =&gt; array( 44 ),
  'category__not_in' =&gt; '44',
  'category__not_in' =&gt; 44,
  </code></pre>
  
  <p>But nothing works     =(</p>
