We'll create fresh WordPress site with Disable XML RPC Fully installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Simple plugin that disables XML-RPC, since it is enabled by default on WordPress 3.5 and above. It also removed references in the headers and in the body of the html.
If you wish to follow the development of this plugin, view the code on the official plugin website or follow me on twitter @thespacedmonkey
