<p>Uses PHP’s output buffering to buffer XML-RPC responses and strip superfluous whitespace.</p>
<p>Plugins, themes, and any other files executed during the WordPress load process can unintentionally emit whitespace,<br />
such as by including a newline character after an explicit closing “?>” PHP tag instead of letting PHP auto-close the<br />
file.</p>


XML-RPC De-whitespacer

Removes leading and trailing whitespace from XML-RPC responses that can break some XML-RPC clients.

<h4>What Is xmlrpc.php?</h4>
<p><a href="http://www.xmlrpc.com/" rel="nofollow ugc">XML-RPC</a> is a remote procedure call (RPC) protocol, a feature included in WordPress, which enables data to be transmitted. It uses HTTP as the transport mechanism, and XML to encode its calls.</p>
<p>Unless you use remote technologies and mobile applications to update your WordPress site, you might not be familiar with XML-RPC. For the uninitiated, you can use xmlrpc.php to establish a remote connection to WordPress, and make updates to your site without directly logging in to your WordPress system.</p>
<p>XML-RPC is indeed useful for enabling remote connections between various external applications and WordPress. On the other hand, disabling this feature can help improve your site’s security.</p>
<h4>Why You Should Disable xmlrpc.php?</h4>
<p>The problem is that xmlrpc.php poses a security risk. It creates an additional access point to your site, which could leave it vulnerable to external attacks. Every time you authenticate XML-RPC, you need to supply your username and password. As you can imagine, this isn’t exactly ideal for security purposes.</p>
<p>For example, in order to prevent brute force attacks, you can limit login attempts on your WordPress site. However, with XML-RPC enabled, that limit does not exist. There’s no capping on login attempts, which means it’s only a matter of time before a determined cybercriminal gains access.</p>
<p>By disabling the feature, you are closing a potential area of entry for hackers.</p>
<p>XML-RPC functionality is turned on by default since WordPress 3.5. This plugin simply disables only the XML-RPC API Pingback Methods used by hackers on a WordPress site, providing an easy and simple way to disable/enable XML-RPC API Pingback Methods without completely disabling the XML-RPC API, which is used by some plugins and applications (i.e. mobile apps or a few Jetpack modules).</p>
<h4>Features</h4>
<p>Removes the following methods from the XML-RPC API interface.</p>
<ul>
<li>pingback.ping</li>
<li>pingback.extensions.getPingbacks</li>
<li>X-Pingback from HTTP headers</li>
</ul>
<h4>Requirements</h4>
<ul>
<li>WordPress 3.8.1 or higher.</li>
