A Step-by-Step Guide on Enabling Debugging In WordPress True for Enhanced Performance


In the world of WordPress development, troubleshooting issues effectively is key to maintaining a high-performing website. One of the most powerful tools at your disposal is the debugging feature. Enabling debugging allows you to uncover hidden errors, track down issues with plugins or themes, and ultimately ensure a smoother user experience on your site.

WordPress is a powerful content management system that fuels millions of websites across the internet. While it’s user-friendly and feature-rich, like any software, it may encounter issues from time to time. To troubleshoot and resolve these issues effectively, WordPress provides a handy tool called WP_DEBUG. In this article, we’ll explore the benefits of enabling WP_DEBUG and how it can significantly simplify the debugging process.

Why Enable Debugging?

Debugging in WordPress provides invaluable insight into what’s happening behind the scenes of your website. By default, WordPress suppresses PHP errors and warnings for end-users, which is ideal for a production site but can hinder development and troubleshooting efforts. When you enable debugging, PHP errors are displayed, making it easier to identify and resolve issues promptly.

WP_DEBUG is a constant or debugging in WordPress that, when set to true, activates the debugging mode. This mode helps developers identify and address issues by displaying error messages and warnings directly on the screen. It is a valuable tool during the development phase, allowing you to catch and fix problems before they become critical.

Enabling WP_DEBUG:

Enabling WP_DEBUG is a straightforward process. Simply open your wp-config.php file, which is located in the root directory of your WordPress installation. Look for the following line:

wp config php
define( 'WP_DEBUG', false );
debug true wordpress config php

By setting WP_DEBUG to true, you instruct WordPress to report any PHP errors, warnings, and notices on your site. This information can be instrumental in identifying issues with themes, plugins, or custom code.

Benefits of WP_DEBUG:

  1. Error Identification: When WP_DEBUG is enabled, WordPress will display error messages on the screen, making it easier to identify the root cause of issues. These messages provide detailed information about the problem, helping developers pinpoint and resolve issues quickly.

  2. Plugin and Theme Debugging In WordPress: WP_DEBUG is particularly useful for troubleshooting problems related to plugins and themes. By highlighting errors or conflicts, developers can streamline the debugging process, ensuring a smooth user experience.

  3. Performance Optimization: Identifying and resolving errors early in the development phase contributes to a more optimized and efficient website. WP_DEBUG aids in maintaining the overall performance of your WordPress site by addressing issues before they impact the end-user experience.

  4. Security Enhancement: Debugging In WordPress is not only about fixing errors but also about enhancing the security of your WordPress site. WP_DEBUG allows you to spot vulnerabilities and potential security threats, enabling you to take proactive measures to secure your website.

Best Practices for Using WP_DEBUG:

  1. Disable on Production Sites: While WP_DEBUG is invaluable during development, it’s crucial to disable it on live or production sites. Displaying error messages on a live website can expose sensitive information and compromise security.

  2. Use WP_DEBUG_LOG: In addition to displaying errors on the screen, you can log them to a file by adding the following line to your wp-config.php file:

define( 'WP_DEBUG_LOG', true );

This creates a debug.log file in your wp-content directory, allowing you to review errors in a more controlled environment.


Enabling WP_DEBUG or debugging in WordPress is a powerful technique for developers to identify and resolve issues efficiently. By providing real-time error messages and warnings, this debugging tool facilitates a smoother development process, ensuring a more robust and secure website. Remember to use WP_DEBUG responsibly, disable it on live sites, and leverage additional features like WP_DEBUG_LOG for comprehensive debugging. With WP_DEBUG at your disposal, you’ll be better equipped to create and maintain high-quality WordPress websites.
