In this guide, we’ll explore the methods to disable XML-RPC in WordPress and enhance the security of your website.
10. What is XML-RPC in WordPress? XML-RPC (Extensible Markup Language Remote Procedure Call) is a remote communication protocol used by WordPress to enable cross-platform communication between different systems. It allows external applications or services to interact with your WordPress site, such as publishing content remotely or accessing site data.
11. Why Disable XML-RPC? Despite its usefulness, XML-RPC can also be exploited by hackers to carry out brute force attacks, DDoS attacks, and other malicious activities. To mitigate these risks, many WordPress users prefer to disable XML-RPC if they don’t need its functionalities.

Now, let’s explore various methods to disable XML-RPC in WordPress step by step:

4. Method 1: Disable XML-RPC Using a Plugin: Step 1: Log in to your WordPress admin dashboard. Step 2: Navigate to “Plugins” in the left sidebar and click on “Add New.” Step 3: In the search bar, type “Disable XML-RPC” and press “Enter.” Step 4: Install and activate a suitable plugin like “Disable XML-RPC” or “Disable XML-RPC by Rank Math.” Step 5: Once activated, XML-RPC will be disabled automatically.
5. Method 2: Disabling XML-RPC via .htaccess: Step 1: Access your website’s files using an FTP client or cPanel File Manager. Step 2: Look for the .htaccess file in your website’s root directory.

Step 4: Open the functions.php file using a text editor. Step 5: Add the following code snippet at the end of the file:

phpCopy code// Disable XML-RPC
add_filter('xmlrpc_enabled', '__return_false');

Step 6: Save the changes and upload the updated functions.php file back to your server.
