In the sidebar, child (or sub) pages are not being displayed. Any clues? The code is as follows
<h2 class="hide">Main menu:</h2>
<ul class="page">
<?php if (is_page()) { $highlight = "page_item"; } else {$highlight = "page_item current_page_item"; } ?>
<li class="<?php echo $highlight; ?>"><a href="<?php bloginfo('url'); ?>">Home</a></li>
<?php wp_list_pages('sort_column=menu_order&depth=1&title_li='); ?>
</ul>
