I have lately upgraded wordpress to three.3 version and also the navigation isn't working anymore because I've spans tags in to the menu link added with link_after and link_before.

Also wp_list_pages("title_li=&child_of=".$post->ID."&echo=0"); isn't working but wp_list_pages("title_li=&child_of=".$post->post_parent."&echo=0"); is working. All I want may be the the submenu for that parent list.

Any ideas?
