Zen sub theme: page--node--name.tpl.php not working!
Drupal doesn't provide content type based template suggestions for page.tpl.php but for node.tpl.php. That means you can use a template like node--custom-content-name.tpl.php.

However, if you want to have a page.tpl.php for your content type, you need to tell Drupal about your template suggestion. Put this code in your template.php file:

function YOURTHEME_preprocess_page(&amp;$variables) {
  if (isset($variables['node']-&gt;type)) {
    $content_type = $variables['node']-&gt;type;
    $variables['theme_hook_suggestions'][] = 'page__' . $content_type;
  }
}


You should name your template file like: page--custom-content-name.tpl.php.
