Disable XML-RPC的作者是Philip Erb,目前有100,000+个有效安装。已经Tested with 5.1.5版本的wordpress。
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.
