title: Wordpress theme customizer - can't add section/settings
body: <p>I'm trying to modify the Worpdress theme customizer by adding sections and settings but no matter what I add in my functions.php file, nothing ever shows up in the customizer.</p>
  
  <p>Example:</p>
  
  <pre><code>function starter_customize_register( $wp_customize ) 
  {
      $wp_customize-&gt;add_section( 'mytheme_new_section_name' , array(
      'title'      =&gt; __( 'Visible Section Name', 'starter' ),
      'priority'   =&gt; 30, ) );    
  }
  add_action( 'customize_register', 'starter_customize_register');
  </code></pre>
  
  <p>I would have expected this to add a section with the chosen name but the only things I see are the two initial sections from Wordpress (site title &amp; tagline, static front page).</p>
  
  <p>I had found a pretty nice tutorial here (<a href="http://code.tutsplus.com/series/a-guide-to-the-wordpress-theme-customizer--wp-33722" rel="noreferrer">http://code.tutsplus.com/series/a-guide-to-the-wordpress-theme-customizer--wp-33722</a>). I followed every step and even took their example theme but there again, no new sections or settings are displayed.</p>
  
  <p>Makes me wonder if something is wrong with my configuration.</p>
  
  <p>I'm using a wordpress network/multisite, don't know if that's relevant.</p>
  
  <p>Any idea?</p>
  
  <p>Thanks
  Laurent</p>
