Debugging WordPress trackbacks and pingbacks

These days I needed to debug WordPress trackbacks and pingbacks. It is not that straight forward because it uses RPC. Hopefully, there is a neat way to log the calls.

It looks like WP SpamFree is blocking some legitimate trackbacks and pingbacks. Reaching this conclusion wasn't easy until I found that you can enable XML-RPC logging by setting $xmlrpc_logging true in xmlrpc.php.

Right now I'm trying to track SpamFree problems. Keep you posted.

Later edit: looks like I was wrong about spam free. The pingback broblem was related to the fact that wp-cron.php wasn't called.
