Whenever somebody pingbacks some of my articles, this is not recognized by WP, meaning that the pingback is not inserted into the comment table. Looking up the log files, everthing seems OK (there is code 200) when xmlrpc.php is called.
Well, as far as I understand the concept of pingback, code 200 doesn't mean too much here, since a possible error is reported in the output (XML) of the call to xmlrpc.php.
What might this be? Is there a way to actually see the output of a pingback to give me further hints? I'm running WP 1.2.2 on Debain Woody with PHP 4.1.2.
