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. The WordPress mobile app should tell you that “XML-RPC services are disabled on this site” if the plugin is activated.
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.

Something doesn’t seem to be working correctly

If the plugin is activated, but XML-RPC appears to still be working … OR … the plugin is deactivated, but XML-RPC is not working, then it’s possible that another plugin or theme function is affecting the xmlrpc_enabled filter. Additionally, server configurations could be blocking XML-RPC (i.e. blocking access to xmlrpc.php in the .htaccess file).
