It seems impossible to trackback a post of my wordpress blog from another blog, what can I do?. If for instance try to ping a post from Haloscan I get the following error:
Pinging http://nightpassage.free.fr/wp-trackback.php/126... Malformed response: (Target does not appear to be a valid trackback URL).
Then I have also tried from another blog but with no success. Can this depend from free.fr? thanks for any help
