I'm getting the same error. However it did work at one time before I "restored" my site... weird. The content seems to be ok...except when updating the feeds @ http://www.binaryechoes.net/wp-content/update-feeds.php I get
update-feeds: instruct FeedWordPress to look for new syndicated content
Sending ping to <http://www.binaryechoes.net/xmlrpc.php>...
The XML-RPC ping failed (local): transport error - could not open socket
I tried reinstalling the plugin and searching WP forums to no avail.
Is this a bug or is it something that I'm overlooking?
Any suggestions and/or hacks greatly appreciated...
