title: excerpt length in Child Theme
body: <p>Once again my amature php skills have me pinned down by its strings!</p>
  
  <p>I am trying to change the excerpt length of the post summaries on my Wordpress blog page. So far I have created a child theme, replaces the content.php file code to</p>
  
  <pre><code>&lt;div class="entry-content"&gt;
              &lt;?php the_excerpt( __( 'Continue reading &lt;span class="meta-nav"&gt;&amp;rarr;&lt;/span&gt;', 'twentyeleven' ) ); ?&gt;
              &lt;?php wp_link_pages( array( 'before' =&gt; '&lt;div class="page-link"&gt;&lt;span&gt;' . __( 'Pages:', 'twentyeleven' ) . '&lt;/span&gt;', 'after' =&gt; '&lt;/div&gt;' ) ); ?&gt;
          &lt;/div&gt;&lt;!-- .entry-content --&gt;
  </code></pre>
  
  <p>and added a functions file with the following code </p>
  
  <pre><code>    &lt;?php
  
  function CHILDTHEME_excerpt_length($length) {
      return 600;
  }
  add_filter('excerpt_length', 'CHILDTHEME_excerpt_length'); ?&gt;
  </code></pre>
  
  <p>AND what do you know...... It still remains the same length of summary on the blog page as before. What am I doing wrong?</p>
  
  <p>All help is very much appreciated as always</p>
