Hello,
My name is Sergey. I am Freelancer from [login to view URL], Russia.
I can help you as a WordPress programmer to repair xml-rpc feature. So, you can be able to use your article poster again, like it was before latest upgrade.
I need FTP access to start right now. And login/password into "wp-admin" Dashboard.
I can communicate via Freelancer.com.
