Debugging in WordPress is essential for keeping your website running smoothly and free of errors. Whether you're an expert or a beginner, learning to use WordPress's built-in debug tools is key to better troubleshooting.

What is WordPress Debug Mode?

WordPress Debug Mode is a feature that helps you find and fix problems on your website. When you turn it on, it shows detailed error messages, warnings, and notices. This makes it easier to understand what's wrong and fix it, so your website runs smoothly. It's useful for developers and anyone who wants to keep their WordPress site in good shape.

When Should You Enable WordPress Debug Mode?

You should enable WordPress Debug Mode in the following situations:

• During Development: When building or customizing your site, catch and fix errors early.

• Troubleshooting Issues: When your site is experiencing problems, identify the source of errors, warnings, or notices.

• Testing New Plugins or Themes: Before making them live, ensure compatibility and functionality without errors.

• After Updates: Following updates to WordPress, themes, or plugins, to catch any new issues that may arise.

Remember to disable Debug Mode on a live site to prevent displaying sensitive information to visitors.

How to Enable WordPress Debug Mode in native WordPress

Before we get into how to enable WordPress Debug Mode, let's look at the different ways to activate it.

If you're comfortable with the code, you can manually edit the wp-config.php file using SSH or an SFTP client. Another easy method is to install a WordPress plugin called WP Debugging.

Here's a quick explanation of the PHP flags we'll use:

• WP_DEBUG: Turns on debug mode.

• WP_DEBUG_LOG: Saves error messages to a debug log file.

• WP_DEBUG_DISPLAY: Controls whether error messages are shown on the website.

Now, let's move on to the step-by-step guide.

How to Enable WordPress Debug Mode in Composer-based WordPress

Before we get into how to enable WordPress Debug Mode, let's look at the different ways to activate it.

If you're comfortable with code, you can manually edit the .env file using SSH or an SFTP client. Another easy method is to install a WordPress plugin called WP Debugging.

Here's a quick explanation of the environment variable flags we'll use:

• WP_ENV='production': Turns off debug mode

• WP_ENV=’staging’: Turns off debug mode

• WP_ENV=’development’: Turns on debug mode

Now, let's move on to the step-by-step guide.

Prerequisites

• A basic understanding of SFTP (Secure File Transfer Protocol) and SSH (Secure Shell) is essential for accessing and editing files on Cloudways.

• It is necessary if you understand the structure and content of the wp-config.php file, as it is where WordPress Debug Mode settings will be modified.

• Please be aware of the risks associated with debugging, as enabling Debug Mode exposes detailed error information, including sensitive data.

Alternatively, you may also seek help from your web developer if you are uncomfortable handling this to ensure proper execution without compromising site security or functionality.

Important Note

We recommend taking an application backup before editing the wp-config.php file, which requires precision and care. Having a backup is a proactive measure to ensure your site's safety and integrity. You can also restore your application to a previous point if unforeseen issues arise.

If you are using WeWP hosting, here are the steps on how to enable WordPress debug mode.
