Pingbacks not working

Pingbacks don’t work for me, neither incoming nor outgoing. Enabling logging in xmlrpc.php and making sure the logfile is word-writable produces nothing but an empty logfile.

My blog is on lighthttpd, using pretty permalinks and the following mod_rewrite rules:

$HTTP["host"] =~ "mriedel\.org" {
        url.rewrite-once = (
                # Exclude some directories from rewriting
                "^/([a-z]{2}/)?((wp-admin|wp-includes|wp-content|files)/.*)" => "/$2",
                # Exclude .php files at root from rewriting
                "^/([a-z]{2}/)?([^/]*\.php)" => "/$2",
                # Handle permalinks and feeds (qTranslate)
                "^/([a-z]{2})/(.*)$" => "/index.php/$2?lang=$1",
                # Handle permalinks and feeds (no qTranslate or qTranslate default language)
                "^/(.*)$" => "/index.php/$1"
        )
}

imo, those rules should cover xmlrpc.php. I can reach mriedel.org/xmlrpc.php in the browser, so it should be fine.

plugins installed and activate:

– qTranslate
– all in one SEO pack
– statPress
– WP-Syntax
– WP Security Scan

Any help appreciated 🙂

Edit: trackbacks don’t work either

Edit2: an incoming testback test produced the following in the logfile:

yet no trackback is shown.
