I've been trying to ping/send trackbacks to various places, but they don't seem to go through.
Normally, if a trackback goes through, I'd see the TB link in the "already pinged" section when I edit the post. This time, no matter how many times I edit & save, it still doesn't ping.
I've noticed that WP tries to TB links in posts, but this seems to be on-and-off for me. I've linked to my own posts before, and some get the Pingback notification while some don't.
What's going on? Is there a problem with the Trackbacks? How can I make my Trackbacks go through?
