First it was the problem with the vanished child links and the stray raquo... I fixed that OK, and got the links to look all right. But then I tried to validate it and got a bunch of errors saying that the li tags were not allowed to be where they were (incorrect nesting). I have NO idea how to fix this. I tried removing the li tags, but the validation errors persisted, so I figured the PHP includes folder was hiding some li tags. I tried to edit them out, but of course I got a PHP error.
Can anyone help? My sidebar code is located at http://www.a-splode.net/wp-content/themes/default/sidebar.php and the validation results for one of my pages are here:
