Why Tracking WordPress Errors Matters

Every WordPress website can encounter errors at some point. From plugin conflicts to theme incompatibilities, these issues can disrupt your site’s performance and user experience. Thankfully, WordPress provides a built-in logging system to help you identify the root cause of problems and fix them efficiently.

At WPbyLondon, a trusted wordpress development agency london, we regularly leverage WordPress logs to troubleshoot issues, ensuring our clients’ websites stay secure and fully functional.

In this guide, we’ll explain why enabling WordPress logs is essential and provide a step-by-step method to set them up on your own site.

Why You Should Enable WordPress Error Logs

WordPress logs, also known as debug logs, provide a record of any errors or warnings generated by your website. These logs are invaluable when diagnosing problems or when seeking help from the community. Even with high-quality plugins and themes, conflicts can arise, and logs give you the information needed to resolve them quickly.

By using error logs, you can:

• Track the source of a problem
• Reduce downtime by fixing issues faster
• Provide detailed information when asking for support online

Whether you are troubleshooting on your own or consulting forums, logs make the process significantly easier.

Step-by-Step: How to Enable WordPress Logs

Enabling WordPress logs is straightforward but requires careful handling. Before proceeding, back up your website and, ideally, perform these steps on a staging environment. This ensures no live site functionality is affected if mistakes occur.

Step 1: Access Your Website Files

First, you need access to your website’s files. The most common method is through an FTP client. FileZilla is a reliable, free option for this purpose.

Steps:

1. Download and install FileZilla.
2. Enter your FTP credentials (host, username, password). These are provided by your hosting provider.
3. Connect to your server and navigate to your website’s root directory.

This gives you full access to your WordPress files, including wp-config.php.

Step 2: Edit wp-config.php

The wp-config.php file controls critical WordPress settings. To activate logging:

1. Locate wp-config.php in your root directory.
2. Open it in a text editor.
3. Add the following lines above /* That’s all, stop editing! Happy blogging. */:

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

The first line enables debugging mode, while the second tells WordPress to create a log file for errors. Save the file and upload it back to the server when prompted.

Step 3: Locate and Use Your WordPress Logs

Once enabled, WordPress will create a debug.log file inside the wp-content folder. To use it effectively:

1. Reproduce the issue: Logs only record errors after logging is active. Trigger the problem on your site so it gets recorded.
2. Access the log: Open wp-content/debug.log via FTP or your hosting file manager.
3. Analyze the errors: The log lists all warnings and errors, often pointing to the plugin, theme, or file causing the problem.
4. Resolve the issue:
   • DIY approach: If you are familiar with WordPress, you can often fix the error by updating, disabling, or replacing the problematic plugin/theme.
   • Community help: Share the relevant log details on forums for assistance. Many WordPress experts can guide you with specific fixes.

Step 4: Turn Off Logging After Troubleshooting

Leaving debug logs active on a live site is not recommended. It can expose sensitive information and slightly reduce performance. To disable logging, edit wp-config.php again:

define('WP_DEBUG', false);
define('WP_DEBUG_LOG', false);

Save and upload the changes. Your website will continue to function normally without logging every error.
