title: Show WordPress Page outside loop with vc page builder code inside the content
body: <p>I use WordPress inside an extern website
  (with <code>require_once($_SERVER['DOCUMENT_ROOT'] . '/wp-load.php');</code>)</p>
  
  <p>I would like to load a specific page and show the content.</p>
  
  <pre><code>$post = get_post(467, OBJECT);
  
  $content = $post-&gt;post_content;
  $content = apply_filters('wpautop', $content);
  $content = str_replace(']]&gt;', ']]&gt;', $content);
  setup_postdata($post); 
  </code></pre>
  
  <p>...</p>
  
  <pre><code>&lt;article id="post-&lt;?php the_ID(); ?&gt;"&gt;
    &lt;div class="entry-content"&gt;
      &lt;?php echo $content; ?&gt;
      &lt;?php wp_link_pages( array(
                          'before' =&gt; '&lt;div class="page-links"&gt;' . esc_html__( 'Pages:', 'tm-polygon' ),
                          'after'  =&gt; '&lt;/div&gt;',
                          ) );
      ?&gt;
    &lt;/div&gt; &lt;!-- .entry-content --&gt;
  &lt;/article&gt;&lt;!-- #post-## --&gt;
  </code></pre>
  
  <p>...</p>
  
  <p>The problem is: The page content is build by the visual composer page builder plugin and the output is plain vc code, instead of rendering the content.</p>
  
  <p>Like: <code>[vc_row full_width="stretch_row" css=".vc_custom_1472216323117{margin-top: 0px !important;margin-bottom: 50px !important;padding-top: 170px !important;padding-bottom: 165px !important;background-image: url(http://wp.netzexperten.org/wp-content/uploads/2015/09/section14.jpg?id=469) !important;background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;}"][vc_column][vc_column_text el_class="section-title" css=".vc_custom_1443428582908{margin-top: -25px !important;margin-bottom: 0px !important;}"]</code> </p>
  
  <p>I hope you can help me, chris</p>
