If you are using WP 2.7, after entering <link rel=”EditURI” type=”application/rsd+xml” title=”RSD” href=” https://example.com/xmlrpc.php?rsd” /> make sure to enable the option in your wp-admin, under “Options”, in the “Writing” section you will see the option for “XML-RPC”. Make sure you check the box next to it that says “Enable the WordPress, Movable Type, MetaWeblog and Blogger XML-RPC publishing protocols.” After that it should be up and running. Good luck!
