Show empty categories in section

When using Joomla 1.0.x + (not 1.5), if you create a menu item linking to a section – this will list and link to the categories. In the Joomla admin you can select "show empty categories" – but this option wont always work.

To fix this problem find this file: /components/com_content/content.php

Replace this line [about line 326] :
  $access_check_content = "\n AND b.access <= " . (int) $gid;

With this line:          
  $access_check_content = "\n AND ( b.access <= " . (int) $gid ." OR b.access is null)";

Now you will see the categories inside the section even if there are no articles in them.
