For assembly instructions, you’ve got two problems in your statement. One, you don’t have an ampersand (&) separating the title_li argument from the exclude argument. Second, you are using single quote around the whole argument list, but also using single quote inside the argument list. To be honest, I don’t know how WP deals with quoting in such a case. PHP in general is pretty flexible, maybe you just want double quotes:
<?php wp_list_pages(“depth=1&title_li=’,’&exclude=67”); ?>
It would go in the wp_list_pages arguments:
wp_list_pages(‘sort_column=menu_order&title_li= &child_of=’.$post->post_parent.’&exclude=14′);
This used to work in WP 2.3. Apparently it has regressed in 2.6. I have not been able to find an answer yet. Good luck!
