title: wordpress - excluding a category from a post list in a custom theme that doesn't look like the codex
body: <p>I'm hoping someone can help. I'm not a php coder, but I've been tweeking and customising a premium theme for wordpress anyway, and I'm stuck.</p>
  
  <p>I'm trying to exclude a specific category from a page which lists all the categories by default.  Ok, no problem. It should be: </p>
  
  <pre><code>&lt;?php query_posts($query_string . '&amp;cat=-134'); ?&gt;
  </code></pre>
  
  <p>right?  </p>
  
  <p>I'm pretty sure the category number is 134, but I could be wrong. The premium theme I'm using is called Risen, and there's a lot of different kinds of posts - so maybe what I think is a category is really a tag in a custom taxonomy - in which case ??? </p>
  
  <p>When I hover over it in the category listing I get this:</p>
  
  <pre><code>example.com/wp-admin/edit-tags.php?action=edit&amp;taxonomy=risen_multimedia_category&amp;tag_ID=134&amp;post_type=risen_multimedia
  </code></pre>
  
  <p>I'm pretty sure I've found where I need to include my argument, and that is here in the template:</p>
  
  <pre><code>// Get posts
  $multimedia_query = new WP_Query( array(
      'post_type'         =&gt; 'risen_multimedia',
      'posts_per_page'    =&gt; risen_option( 'multimedia_per_page' ) ? risen_option(  'multimedia_per_page' ) : risen_option_default( 'multimedia_per_page' ),
      'paged'             =&gt; risen_page_num() // returns/corrects $paged so pagination works on static front page
  ) );
  </code></pre>
  
  <p>I've tried adding</p>
  
  <pre><code>'tag'   =&gt; -134
  </code></pre>
  
  <p>to this array to no avail.</p>
