title: Custom Post Type Slug Rewrite Issues
body: <p>To put a long story short, I'm trying to get the custom post type category to show where it says 'project-item' as you can see <a href="http://celtexperience.com/project_item/celt-la-tene-3-3-hoppy-bitter-with-video/" rel="nofollow">HERE</a></p>
  
  <p>I presume it has something to do with the way I've registered the custom post type such as in this code:</p>
  
  <pre><code>&lt;?php
  add_action( 'init', 'register_posts' );
  function register_posts() {
  
      register_post_type( 'team_post',
          array(
              'labels' =&gt; array(
                  'name' =&gt; __( "Team" ,"um_lang"),
                  'singular_name' =&gt; __( "Team" ,"um_lang")
              ),
              'public' =&gt; true,
              'has_archive' =&gt; true,              
              'rewrite' =&gt; array('slug' =&gt; "project_item", 'with_front' =&gt; TRUE),
              'supports' =&gt; array('title','editor','thumbnail','page-attributes')             
          )
      );
  
      register_post_type( 'project_post',
          array(
              'labels' =&gt; array(
                  'name' =&gt; __( "Projects","um_lang"),
                  'singular_name' =&gt; __( "Project" ,"um_lang")
              ),
              'public' =&gt; true,
              'has_archive' =&gt; true,              
              'rewrite' =&gt; array('slug' =&gt; "project_item", 'with_front' =&gt; TRUE),
              'supports' =&gt; array('title','editor','thumbnail','page-attributes')             
          )
      );
  
      register_taxonomy('project_category',array (
        0 =&gt; 'project_post',
      ),array( 'hierarchical' =&gt; true, 'label' =&gt; __('Projects Category',"um_lang"),'show_ui' =&gt; true,'query_var' =&gt; true,'singular_label' =&gt; __('Projects Category',"um_lang")) );
  
  }
  ?&gt;
