説明

Pretty simply, this plugin disables the XML-RPC API on a WordPress site running 3.5 or above.

Beginning in 3.5, XML-RPC is enabled by default. Additionally, the option to disable/enable XML-RPC was removed. For various reasons, site owners may wish to disable this functionality. This plugin provides an easy way to do so.

インストール

Upload the disable-xml-rpc directory to the /wp-content/plugins/ directory in your WordPress installation
WordPress の「プラグイン」メニューからプラグインを有効化してください
XML-RPC is now disabled!

To re-enable XML-RPC, just deactivate the plugin through the ‘Plugins’ menu.

FAQ

Is there an admin interface for this plugin?: No. This plugin is as simple as XML-RPC is off (plugin activated) or XML-RPC is on (plugin is deactivated).
How do I know if the plugin is working?: There are two easy methods for checking if XML-RPC is off. First, try using an XML-RPC client, like the official WordPress mobile apps. Or you can try the XML-RPC Validator, written by Danilo Ercoli of the Automattic Mobile Team – the tool is available at http://xmlrpc.eritreo.it/ with a blog post about it at http://daniloercoli.com/2012/05/15/wordpress-xml-rpc-endpoint-validator/. Keep in mind that you want the validator to fail and tell you that XML-RPC services are disabled.
