How to Manage PHP Errors in WordPress: Turning Them On and Off

Introduction

WordPress is a powerful and versatile platform for building websites, but like any software, it’s not immune to errors. PHP errors, warnings, and notices can occasionally pop up, disrupting the user experience and potentially revealing sensitive information about your site’s configuration. Luckily, WordPress provides a way to manage these errors, allowing you to turn them off for a seamless browsing experience or turn them on to debug issues effectively. In this article, we’ll walk you through the process of both turning off and turning on PHP errors in WordPress.

Turning off PHP Errors in WordPress

If you’ve noticed pesky PHP errors, warnings, or notices cluttering your WordPress website, there’s a straightforward solution to hide them from your visitors. Follow these steps to turn off PHP errors:

1. Locate wp-config.php: Navigate to your WordPress installation directory on your server. Inside it, you’ll find the wp-config.php file.

2. Find WP_DEBUG Line: Open the wp-config.php file using a text editor and look for the line that reads: define('WP_DEBUG', true); or define('WP_DEBUG', false);.

3. Edit the Configuration: Replace the existing line with the following code:

ini_set('display_errors', 'Off');
ini_set('error_reporting', E_ALL);
define('WP_DEBUG', false);
define('WP_DEBUG_DISPLAY', false);

1. This code will suppress the display of PHP errors, notices, and warnings on your WordPress website.
2. Save and Upload: After making the changes, save the wp-config.php file and upload it back to your server, replacing the old version.
3. Verify Changes: Visit your website to confirm that the PHP errors, notices, and warnings have disappeared from the site’s front-end.

Turning on PHP Errors in WordPress

While turning off errors can provide a smoother user experience, there are instances when you need to debug your website, especially during development on a local server or staging environment. Here’s how you can turn on PHP errors:

1. Access wp-config.php: Open the wp-config.php file in your WordPress directory.
2. Modify Configuration: Locate the existing code (which you added in the previous section) and replace it with the following:

define('WP_DEBUG', true);
define('WP_DEBUG_DISPLAY', true);

1. Enabling these settings will allow WordPress to display PHP errors, warnings, and notices again.
2. Save and Apply: Save the file after making changes and upload it back to your server.
3. Benefit from Error Reports: With PHP errors turned on, you’ll be able to identify and resolve issues efficiently during development.
