I included this in in my sidebar:
<?php wp_list_pages('title_li='); ?>
The list appeared on the main page of the blog, no problems other than bad style. But when I clicked on the child link (second page), I got this error:
Warning: Invalid argument supplied for foreach() in /home/crowspea/public_html/wp-includes/template-functions-post.php on line 368
I have since removed the the code. There are currently only two pages (I plan to add more), and I am not using a different template other than my default theme template.
Anyone see this before?
