Enabling XML-RPC access to your WordPress.org blog
Many on-line guides (like this one) says to simply go to Settings > Writing and under Remote Publishing to check the XML-RPC protocol checkbox, in order to enable XML-RPC access to your blog.
After that you should be able to access
http://yourblog.com/xmlrpc.php without any problems. When you try to do this via browser, you will most likely see “XML-RPC server accepts POST requests only” message. But, that is still a good news, which clearly confirms that XML-RPC access to your blog is enabled. Otherwise (i.e. without correct enable of XML-RPC) you would hit 403 Forbidden error instead.
If this isn’t working or if you need more fine-grained control over XML-RPC access to your blog then you may find some ideas worth to consider in this short article.Read More “Enabling XML-RPC access to your WordPress.org blog”
