I have a new blog and I've been testing trackbacks to it. I've found that incoming trackbacks only work if the other blog author used:
My blog will not recognize normal pings using the permalink. It will only notice them if /trackback/ is tacked on to the URL.
Now I know that WordPress is *supposed* to work both ways. Even if you simply reference someone else's post in your own post, WP will trackback to it. However, not for my blog. People are referencing my articles but not getting the nod on my site.
Can anyone give me any idea why that might be happening? Why /trackback/ works but the permalink does not?
