Have you ever wondered how to fix those annoying errors on your website? WP Debug is your solution.

WordPress, being the most popular content management system in the world, is not without challenges. From minor errors or conflicts between plugins to more complex issues in the core of the system, every webmaster faces, sooner or later, the need to debug their site. Although it may sound intimidating, debugging is essential for maintaining a healthy and optimized website.

What is WP Debug?

Think of WP Debug as your own digital detective. It’s a tool built into WordPress that helps you identify and solve problems on your site. But why is it so crucial?

Importance of Debugging in WordPress

Think of it this way: if your website is a car, WP Debug is the tool that helps you find those strange noises in the engine. By identifying problems, you ensure that your site operates in the best way possible.

When should I use Debug mode?

1. During development: If you’re building a theme or plugin for WordPress, debug mode will help you identify errors or issues in your code. It’s essential to enable it during this phase to ensure that your code is clean and error-free.
2. Troubleshooting: If your WordPress site starts behaving unexpectedly, activating debug mode can offer clues about what’s wrong. It could be a faulty plugin, a theme causing conflicts, or a problem with the database.
3. Updates: Before and after updating WordPress, plugins, or themes, it’s a good idea to enable debug mode to make sure the updates don’t introduce new problems or conflicts.
4. Optimization: If you’re trying to improve the performance of your site, debug mode, along with other debugging tools, can help you identify scripts or queries that are slowing down your site.
5. Learning and training: If you’re a developer or just someone who wants to learn more about WordPress, enabling debug mode gives you deeper insight into how WordPress works and how different elements interact.

Recommendations:

• Don’t use it on a live site: While debug mode is very useful, it’s not advisable to enable it on a production site where real users can see error messages. This can not only be confusing for them, but it can also reveal information that could be exploited by someone with malicious intentions.
• Use a staging or testing environment: If you can, set up a testing or “staging” environment where you can enable debug mode without affecting real visitors. Here, you can experiment, test, and troubleshoot without fear of breaking your live site.

Configuring WP Debug

Accessing the wp-config.php file

Before getting into action, we need to prepare the ground. The wp-config.php file is like the brain behind your WordPress. This is where we will give it the instructions to start debugging.

1. Access through cPanel:
   • Log into the cPanel of your hosting service.
   • Look for the “Files” section and click on “File Manager.”
   • Navigate to the main folder of your WordPress installation, usually named public_html or the domain name if you have multiple sites.
   • Inside this folder, you should see the file wp-config.php.
2. Access via an FTP client:
   • If you prefer to use an FTP client, like FileZilla, you first need to set it up with the FTP access details provided by your hosting provider.
   • Once connected, navigate to the main folder of your WordPress installation.
   • Here, you will also find the file wp-config.php.

It is important to be very careful when editing or modifying this file.

Activating WP Debug

Let’s get to work! To activate WP Debug, you must add or edit the following line in your wp-config.php file: define('WP_DEBUG', true);
When you activate debug mode in WordPress through the wp-config.php file, you can detect errors, warnings, and notices related to PHP code, scripts, or stylesheets. And remember, it is also possible to show or hide this information in the administration panel or in the public part of your website. You can control it through various WP Debug related constants, such as WP_DEBUG_LOG and WP_DEBUG_DISPLAY.

Deactivating WP Debug

To deactivate WP Debug, simply change the value to false or remove the line altogether: define('WP_DEBUG', false);
