Vypnutí XML-RPC

XML-RPC is a Remote Procedure Call (RPC) protocol which uses XML to encode its calls and HTTP as a transport mechanism. XML-RPC is used to do something remotely to your blog such as posting, viewing comments, etc.
By default, WordPress enables XML-RPC automatically!

Disable XML-RPC Pingback
https://wordpress.org/…pc-pingback/

This is more friendly than disabling totally XML-RPC, that it's needed by some plugins and apps (I.e. Mobile apps or some Jetpack's modules).

Vypnutí pingbacků ve functions.php (totéž jako výše uvedený plugin)

function remove_xmlrpc_pingback_ping( $methods ) {
   unset( $methods['pingback.ping'] );
   return $methods;
}
add_filter( 'xmlrpc_methods', 'remove_xmlrpc_pingback_ping' );

How to disable XML-RPC manually:

  1. turn off XML-RPC in functions.php
add_filter('xmlrpc_enabled', '__return_false');
  1. hide xmlrpc.php in HTTP response headers in functions.php
function disable_x_pingback($headers)
{
  unset( $headers['X-Pingback'] );
  return $headers;
}
add_filter('wp_headers', 'disable_x_pingback');
  1. deny request to xmlrpc.php in .htaccess
<IfModule mod_alias.c>
RedirectMatch 403 /xmlrpc.php
</IfModule>

or

<Files xmlrpc.php>
Order Deny,Allow
Deny from all
</Files>

Mammoth .docx converter
https://wordpress.org/…x-converter/

Mammoth is designed to convert .docx documents, such as those created by Microsoft Word, and convert them to HTML. Mammoth aims to produce simple and clean HTML by using semantic information in the document, and ignoring other details. For instance, Mammoth converts any paragraph with the style Heading1 to h1 elements, rather than attempting to exactly copy the styling (font, text size, colour, etc.) of the heading. This allows you to paste from Word documents without the usual mess.

A simple WordPress plugin to sell digital downloads. It integrates flawlessly with PayPal. User interface (UI) of the plugin is very simple to use, I call this plugin for users, not for developers but developers should not feel left behind. I know how painful it is to modify client's plugins and then find out after a few weeks or months that they had updated the plugin and boom! all changes are lost. There are filters and hooks for almost every important functionality in WP iSell.
