I think I understand WordPress Trac, trying to get all this pingback and trackback stuff fixed. Well, not how to debug and fix code, but how to implement fixes as Ryan and Matt find them.
I’m using revision 2612 of wp-includes/functions-post.php and wp-includes/functions.php Hopefully pingbacks will work.
This is in the series of posts for WordPress 1.5.1 fixes.
Insta-update: No dice. I still didn’t ping that last post. Ah well.
