What are WordPress error logs? How to find, access & debug

Website errors rarely come with clear explanations, especially when you’re working with WordPress. But hidden in your system is a powerful tool that can reveal exactly what’s causing the problem: WordPress error logs. Whether you’re dealing with plugin conflicts, theme issues, or unexpected downtime, knowing how to find and read these logs can save you hours of trial and error.

Let’s walk through how WordPress error logs work and how you can use them to troubleshoot and resolve issues.

What are WordPress error logs?

WordPress error logs are records of error messages generated by your website, each marked with the exact date and time the issue occurred. When WordPress debug mode is enabled, these messages are automatically saved to a file, making it easier to review and troubleshoot later. This logging system is an essential debugging tool that helps you identify problems related to plugins, themes, or custom code and resolve them more efficiently.

What are the benefits of checking your WordPress error logs?Link to heading

Reviewing WordPress error logs is essential when diagnosing and fixing issues on your website. Without clear error details, it’s hard to understand what’s actually going wrong. Here’s why they matter:

  • Identifying problems: Error logs show detailed information about warnings, notices, and errors within your site. This makes it easier to locate the exact source of a problem.
  • Debugging: With clear insights into root causes, developers and site owners can resolve issues faster and more accurately. Without this data, troubleshooting becomes slow and uncertain.
  • Error details: Logs include specific messages, file paths, and line numbers. You can quickly tell whether the issue comes from PHP, JavaScript, or another source, helping pinpoint the problem precisely.
  • Plugin or theme Issues: If errors appear after installing a plugin or theme, logs can reveal conflicts or compatibility problems between components.
  • Performance optimization: Some errors directly impact site speed and responsiveness. Fixing them can improve overall performance.
  • Security: Logs may expose suspicious activity or potential vulnerabilities. Identifying these early helps protect your website.
  • Monitoring site health: Regular checks help maintain stability by addressing small issues before they become serious problems.
  • Documentation and communication: When asking for support, sharing error logs provides clear, actionable information, making collaboration more efficient.

By default, WordPress error logs are disabled, meaning your site won’t record any issues. If you can still access the WordPress dashboard, the easiest way to enable debug mode is by using a plugin.

Steps to follow:

  • Install and activate the WP Debugging plugin
  • Go to Tools → WP Debugging
  • Check “Set WP_DEBUG to true”
  • Click “Save Changes”

Once enabled, the plugin will automatically turn on debug mode and start logging error messages from your website.

This method is better for advanced users or for situations where you cannot access the WordPress admin area. You will need to edit the wp-config.php file using an FTP client or the file manager in your hosting control panel.

After opening the file, find the line that says “That’s all, stop editing! Happy blogging”. Right before that line, add this code:

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

Once you have enabled WordPress debug mode, any future errors on your site will be saved in the WordPress error logs. At first, the log file may be empty, so you will need to reproduce the issue on your website before the error message is recorded. 

Next, connect to your site using an FTP client or your WordPress hosting control panel. After logging in, go to the /wp-content/ folder. There, you will find a file called debug.log. This file contains all recorded WordPress errors, warnings, and notices.

To view the file, you can download it, open it, or edit it directly. Once you read the log entries, check the error messages along with the date and time they occurred. That information can help you identify the cause and find the right solution for the problem on your site.

After fixing issues on your website, it’s recommended to turn off debug mode. Keeping it enabled for too long can slow down your site and expose sensitive information, creating potential security risks.

If you activated debug mode using a plugin, simply go to Plugins > Installed Plugins and deactivate it. If you enabled it manually, edit the wp-config.php file as before and change the values of WP_DEBUG and WP_DEBUG_LOG to false. This will stop generating new WordPress error logs.

You can also disable error logging in your hosting cPanel to avoid storing unnecessary WordPress error logs and help improve overall hosting performance.

ConclusionLink to heading

WordPress error logs give you a clear window into what’s happening behind the scenes of your website. Instead of guessing why an issue occurs, you can rely on real data to understand the cause and fix it with confidence. 

Once you get used to checking and reading error logs, troubleshooting becomes much less stressful and far more efficient. Just remember to enable debug mode only when needed and turn it off after finishing your fixes to keep your site secure and optimized. With this simple habit, you’ll handle WordPress issues more effectively and keep your website running smoothly.

If you want to add an extra layer of security to your website beyond checking WordPress error logs, you can consider installing W7SFW (WordPress Firewall). It is a simple yet effective solution that helps block malicious traffic, reduce attack risks, and protect your website at the perimeter.

One notable point is that W7SFW is designed to be user-friendly, so even if you are not technically skilled, you can still install and use it with just a few basic steps.
