For months now, my blog has been sending screwy trackbacks that have content and tags from one post, but the title and URL of the previous post. I have seen it happen in trackbacks to Technorati and to other blogs. I upgraded to 1.5.2 and there has been no change in this problem.
I previously thought it was technorati's fault, but now I've seen it even with trackbacks to my own blogs being funky, so I know it's WP sending the bad data.
How can I fix this?
