WordPress Trackback Fix

(Esta entrada está en inglés para que su contenido pueda ser leido por más gente. Si alguien tiene problemas para entenderlo, que lo comente y se lo explicaré en castellano)

Here is my solution to the trackback bug on WordPress. I tested it on v1.2 Mingus.

First of all, edit the “wp-includes/functions.php” as mentioned here (english), or here (german), or here (spanish).
Then, edit the file “post.php” under wp-admin folder. I made this changes:

Search for this code and cut the emphasized line:

..
case 'post':
..
  if ($post_status == 'publish') {
..
    do_action('publish_post', $post_ID);
..
  } // end if publish
..

Paste it a little more down, just before the closing of the if:

..
    do_action('publish_post', $post_ID);
  } // end if publish
..

Make the same with the line in the editpost case:

..
case 'editpost':
..
  if ($post_status == 'publish') {
    do_action('publish_post', $post_ID);
..
  } // end if publish
..

Paste it here:

..
    do_action('publish_post', $post_ID);
  } // end if publish
..

This solves the problem for me. I hope that it helps you.

For those that don’t know/want to edit the code, here you have the post.php and functions.php files (zip compressed):
