I’ve just recently noticed that WordPress 1.2 does not send PingBacks from an entry when it has been stored as ‘draft’ and published afterwards.

This seems to be a bug in that version of WordPress – a forgotten line or something.

Here is what to do to get it working (again?):

Find the line that says case 'editpost': in the file wp-admin/post.php and add $post_pingback = intval($_POST['post_pingback']); somewhere after that line. Resulting in something like this:

case 'editpost':
  $post_pingback = intval($_POST['post_pingback']);

Et voila. PingBacks work again…
