I just upgraded to WP 2.7 yesterday. Up until this point, I rarely had trouble posting using Windows Live Writer. However, yesterday I received the following error message right after the upgrade:
The response to the metaWeblog.newMediaObject method received from the weblog server was invalid:
Invalid response document returned from XmlRpc server
I am using WLW 12.0.1366.1026 (and just tried the beta v14 and got the same result). The site hosting my blog is using PHP 5.2.6.
Any suggestions would be helpful. I've tried changing the .htaccess file, modifying the xmlrpc.php file, checked to make sure that the class-IXR.php file is in the wp-includes directory, checked case of filenames. So far nothing has worked. Thanks
