This one's killing me... Trackbacks seem to work, on my own blog and I tested them with RedAlt's trackback tester.
But I can't seem to send trackbacks to blogs running MovableType. (In at least one case, I know for sure the trackback isn't being moderated or censored.)
I'm running WP 1.5.2 (been waiting a bit before I'll bite the bullet and upgrade to 2.0).
Is there any information people can give me that might help?
Something else that would help tremendously -- are there any MovableType test blogs out there which I could try sending trackbacks to? Even better, does anyone have a MovableType blog that I could try sending trackbacks to. (You could even delete the trackbacks if they show up.) I'm just trying to narrow down the problem and figure out what's up.
