usage of theme_more_link in zen template.php I have tried to change the text in the 'Read more' link by putting:

function myzen_more_link($url, $title) {
  watchdog("template.php","myzen_more_link");
  return '&lt;div class="more-link"&gt;' . 
    t('&lt;a href="@link" title="@title"&gt;( more ... )&lt;/a&gt;', 
    array('@link' =&gt; check_url($url), 
    '@title' =&gt; $title)) . '&lt;/div&gt;';
}


In the template.php in my zen subtheme folder but it does not appear to work.

Almost all of the discussions I have seen about formatting the "more_link" concentrate on its placement.  Can anyone tell me why this theme override does not take effect?
What you have done should work. Have you remembered to clear cache?
