Admin Bar goes missing for some pages

Saw other questions/answers/video about this topic. Checked that my user profile is correct, checked the Enfold footer.php and it does appear to have necessary code. (compared what is in the live file vs the original downloaded file…don’t see any difference)

<?php

	/* Always have wp_footer() just before the closing </body>
	 * tag of your theme, or you will break many plugins, which
	 * generally use this hook to reference JavaScript files.
	 */

	wp_footer();

?>
<a href='#top' title='<?php _e('Scroll to top','avia_framework'); ?>' id='scroll-top-link' <?php echo av_icon_string( 'scrolltop' ); ?>><span class="avia_hidden_link_text"><?php _e('Scroll to top','avia_framework'); ?></span></a>

<div id="fb-root"></div>
</body>
</html>

I use a child theme (see the functions.php file below). I don’t think I screwed anything up there, because it has been the same since the site went up. This sometimes appearing/disappearing on certain pages has just started.
Strangely, the admin bar is there for the top level pages. However, in the drop down sub-menu, I lose the admin bar on many of those pages. Can you tell me where to start to track this down please?
