How to Create and Access Error Logs for WordPress

Why Most Website Owners Don’t Know About Error Logs for WordPress?

WordPress is a fairly easy-to-manage CMS. However, you cannot be sure that everything will go according to your plan. When things go wrong, you need something that can guide you in the right direction.

Error logs for WordPress can report to the administrator what is causing the errors. This makes the life of your maintenance team extremely easy.

All the problems that can happen on your website are now easier to troubleshoot. However, sometimes these error logs are now on by default and they need to be turned on manually.

Most businesses are not even aware of the existence of error logs on the platform. They don’t know how it can benefit them and that they are not turned on by default.

A positive side of this story is that error logs for WordPress are easy to enable and view. Overall, they make troubleshooting any WordPress site extremely easy.

It is difficult to assess an initial error message because one problem can have many causes. The error log provides a far more accurate and in-depth description of what is going wrong.

An error log helps you know whether a plugin or theme is causing the problem or if it is your site’s server. Cyber attacks are becoming extremely popular and some of the most popular attacks like DDOS attacks overload the site’s server so that it can stop functioning. If your web server has been attacked by a cyber attack, then not much can be done by you or the service provider.

Websites can also have errors when the servers are temporarily down. If your service provider is not up to the task, you should consider making a switch.

Basically, there are a lot of reasons that your website can have an error in loading. To ensure that your website keeps running error-free, you need to learn how to create and access error logs for WordPress.

How to create error logs for WordPress?

Step 1: Find the WP-config.php file

Go to the cPanel of your website. Before you make a move, it is necessary to create a backup of your site to restore a WordPress site. This way if you make any mistake, you can always load the previous version.

Once you log into the cPanel, click on the file manager. The file manager provides access to all the files that are related to your website. Find the wp-config.php file in the file manager.

Click on the public_html directly. Select the edit option after right-clicking the wp-config.php file. After this, a pop-up window will appear to warn you about creating a backup before proceeding further.

Click on the edit button. A new tab will open which will contain all the code from the wp-config.php file.

Step 2: Activate debug mode

Scroll to the bottom of the code. Paste the following code before the ending.

define( ‘WP_DEBUG’, true );
define( ‘WP_DEBUG_LOG’, true );

It is possible that the first line is already present in the code but if its value is false, you should set it to true. With the help of the first line, WordPress can now debug errors.

While with the second line, you can create an actual log or record of all the errors that you encounter on your site.

You can see the errors in your error log, but you can also get notifications about such errors in your WordPress cPanel. Once the code has been inserted into the file, save the changes, and leave.

Now you will have to view the error logs to assess any problems.

Where can you find the error logs in WordPress?

The error logs can be found in the wp-content folder. When you get to the folder, go to the debug.log file. This contains information on the different errors that your web pages have encountered.

If everything has been going smoothly for your website, you will not see this file. It only appears, when one of your web pages has an apparent error. If you see this file, you should get to work and decide how you plan to resolve the error.

If you ever feel like you don’t need the error logs, you have to go back to the wp-config file and change the value from true to false. Then, everything will be back to how it was before. Having the debugging mode is recommended if you have an in-house team that handles the different aspects of your website.

By following these steps, you can enable debug mode and create an error log for your WordPress website. If you are working alone on your website, this should help you stay on top of things. Because if things go wrong, it will take you a long time to figure out how to get your site back online.

How can you access your error logs?

There are two types of error logs when it comes to a WordPress website. One has to be activated and the other is already active in default mode and can be accessed through the cPanel.

Since they are found in the cPanel, these error logs are focused more on the hosting environment. While the ones found on WordPress report mostly all errors related to your site.

Go to the metrics section of your cPanel and click on the errors option. This file will display up to 300 errors or 2 MB worth of data.

The error log has different information like date, time, and IP address, but typically people are looking for the error message. Because that can reveal the type of error your website encountered.

Once you discover the most common errors that your site faces. You can fix them off one by one. One of the most common errors found on the cPanel error logs is file not found errors.

In this case, you can fix the error by changing or adding the link to the file. Files are often moved around on a website, so it is common that such errors will take place. However, you have to make these changes on cPanel while you change the site on the front end. This way your site is in sync and can run perfectly when a visitor loads it on their device.

Providing a good customer experience is the key to gaining new customers and retaining the old ones. You can do all that by creating and accessing the existing error logs.

Why it is necessary to have access to error logs?

You will face many WordPress errors that can create downtime for your site and decrease customer satisfaction. An error log will reveal which script, plugin, theme, or file is causing the error.

If you have all the information, your team can proactively work to stop any downtime or improve recovery efforts when your site faces downtime.

It is absolutely worth it to activate the error logs because they will tell you which type of error is harming your website.

An additional bonus is that they will also reveal which error happened because of the web host. So, you will know exactly when to switch your web host and move on to a more reliable service provider.

Why Most WordPress “Error Log Guides” Fail You

Most WordPress error log tutorials stop at the same surface-level advice:

• “Enable WP_DEBUG”
• “Check debug.log in wp-content”
• “Use a plugin to view errors”
• That’s useful—but incomplete.

Because in real websites, error logs are not just a file. They are a live diagnostic system that tells you:

• Why your site broke at 2 AM
• Which plugin quietly started failing after an update
• Whether your server is struggling under load
• If your theme is leaking fatal PHP errors in production

In this guide, we’ll go far beyond setup instructions and turn WordPress error logging into a structured debugging system you can actually use in real projects.

1. Understanding WordPress Error Logs as a System (Not a File)

• A WordPress error log is not just “debug.log”.
• It is a collection of signals generated from different layers:
• WordPress Core (functions, hooks, updates)
• Plugins (conflicts, deprecated functions, fatal errors)
• Themes (template failures, missing functions)
• PHP runtime (memory issues, syntax errors)
• Server environment (timeouts, permissions, database issues)

Instead of thinking:

“Where is the error log?”

Start thinking:

“Which layer of my system is failing?”

That shift alone improves debugging speed dramatically.

2. The Real Anatomy of a WordPress Error Log

A typical debug entry looks simple:

[14-Apr-2026 10:22:31 UTC] PHP Fatal error: Uncaught Error: Call to undefined function get_header()

in /wp-content/themes/mytheme/page.php on line 12

But this single line contains multiple layers of intelligence:

1. Timestamp

Tells you when the issue started

2. Error Type

• Notice (low impact)
• Warning (medium impact)
• Fatal error (site-breaking)

3. Message

The actual problem:

• missing function
• invalid argument
• memory exhaustion

4. File Path

This is critical:

• /themes/ → theme issue
• /plugins/ → plugin issue
• /wp-includes/ → core issue

5. Line Number

Pinpoints exact failure location

• Most beginners ignore the file path.
• Professionals start debugging from it.

3. Where WordPress Error Logs Actually Live (Real-World View)

There is no single fixed location. It depends on your hosting architecture.

Common locations:

1. WordPress Debug Log

/wp-content/debug.log

2. Server-Level Logs

• Apache: /var/log/apache2/error.log
• Nginx: /var/log/nginx/error.log

3. PHP Logs

• php_error.log
• hosting-specific directories

4. cPanel Hosting

• “Errors” section in dashboard
• public_html/error_log

5. Managed Hosting (WP Engine, Kinsta, etc.)

Dashboard-based log viewers (no file access)

4. How to Enable WordPress Error Logging (Proper Way)

Instead of blindly enabling debug mode, use a structured setup.

Add this to wp-config.php:

• define(‘WP_DEBUG’, true);
• define(‘WP_DEBUG_LOG’, true);
• define(‘WP_DEBUG_DISPLAY’, false);
• @ini_set(‘display_errors’, 0);

Why this configuration matters:

• Errors are logged, not displayed
• Users don’t see system issues
• Developers still get full visibility

This is production-safe debugging.

5. The Biggest Mistake: Treating Error Logs as Reactive Data

Most people open logs only AFTER something breaks.

That is reactive debugging.

Professional workflow is different:

Pro approach:

• Monitor logs continuously
• Identify patterns early
• Fix issues before they become fatal errors

Example:

Instead of:

“Site is down, check logs”

You detect:

“Plugin X has been generating warnings for 3 days → likely crash incoming”

6. Reading Error Patterns (The Skill Nobody Teaches)

A single error is not important.

A pattern is.

Example pattern:

• Warning: Invalid argument supplied for foreach()
• Warning: Undefined index: user_id
• Warning: Trying to access array offset

This usually means:

• broken API response
• malformed database data
• plugin conflict

One error = bug

Repeated errors = system instability

7. Why Your WordPress Error Log May Not Be Showing

This is one of the most searched problems.

Common reasons:

1. WP_DEBUG not enabled

Without it, logs won’t generate.

2. File permission issues

WordPress cannot write to /wp-content/

3. Hosting restrictions

Some hosts disable logging for performance/security.

4. No errors occurred yet

Yes—empty logs are normal.

5. Wrong environment file

You edited wrong wp-config.php

8. The Performance Impact of Error Logging (Hidden Problem)

Logging is not free.

What happens when logging is enabled:

• Increased disk writes
• Larger debug files
• Potential I/O overhead on shared hosting
• Memory tracking overhead (especially with SAVEQUERIES)

When it becomes a problem:

• debug.log reaches hundreds of MB
• continuous PHP warnings flood file
• slow shared hosting environments

Best practice:

• Enable logging only when needed
• Rotate logs regularly
• Disable display errors in production

9. How Professionals Debug WordPress Issues (Real Workflow)

Instead of randomly checking logs, follow this workflow:

Step 1: Identify symptom

• 500 error
• white screen
• login failure

Step 2: Check log timestamp

Find last error before issue started

Step 3: Identify source layer

• plugin
• theme
• core
• server

Step 4: Isolate component

• deactivate plugin
• switch theme
• test again

Step 5: Confirm resolution

verify logs stop generating errors

10. Plugin vs Theme vs Core Error Identification

This is where most beginners struggle.

Plugin error example:

/wp-content/plugins/contact-form-7/

Theme error example:

/wp-content/themes/astra/

Core error example:

/wp-includes/

Rule of thumb:

• plugins = functionality issues
• themes = layout/render issues
• core = system-level problems

11. When Error Logs Help Solve 500, 403, and 404 Issues

500 Internal Server Error

Usually:

• PHP fatal error
• memory exhaustion

plugin crash

403 Forbidden

Often:

• file permission issues
• security plugin blocking access

404 Not Found

Typically:

• permalink issues
• missing routes
• deleted pages

Error logs often reveal the hidden root cause, not just the symptom.

12. Advanced Technique: Turning Logs into a Debugging Dashboard

Instead of manually checking logs, advanced developers:

• Aggregate logs into external tools
• Send alerts to email/Slack
• Monitor error spikes
• Track recurring issues

This transforms WordPress from:

reactive troubleshooting system

to:

proactive monitoring system

13. Best Practices for WordPress Error Logging

Do:

• Enable debug logging only when needed
• Monitor plugin updates carefully
• Rotate logs regularly
• Secure log files from public access

Don’t:

• Leave WP_DEBUG enabled in production
• Ignore repeated warnings
• Let debug.log grow indefinitely
• Share logs without sanitizing sensitive data

Stop Treating Logs as Debug Files—Start Treating Them as Intelligence

WordPress error logs are not just technical outputs.

They are a real-time intelligence layer for your website health.

If you only use them when your site breaks, you’re reacting too late.

If you monitor and interpret them correctly, you can:

• Prevent crashes before they happen
• Identify plugin conflicts early
• Improve performance stability
• Secure your site from hidden failures

The difference between a beginner and an advanced WordPress developer is simple:

• Beginners read error logs
• Professionals underst.and system behavior from them.
