How to Fix WordPress 500 Internal Server Error (Beginner‑Friendly Guide)

WordPress 500 Internal Server Error

You open your WordPress site, expecting it to load like usual…
Instead, you’re greeted with a frustrating message:

“500 Internal Server Error.”

No explanation.
No guidance.
Just a broken site and rising panic.

If you’re a beginner, this error can feel terrifying. The good news?
The WordPress 500 Internal Server Error is common – and completely fixable.

In this guide, I’ll walk you through exactly what causes this error and show you step‑by‑step solutions, explained in simple language – no technical background required.

Let’s fix your site calmly and correctly.

What Is the WordPress 500 Internal Server Error?

The 500 Internal Server Error is a generic server-side error.
It means your server knows something went wrong — but doesn’t know how to explain it clearly.

Think of it like this:

Your website asked the server to do something,
and the server responded with:
“Something broke… I can’t tell you what.”

This makes the error confusing, but it also narrows the problem down to a few common causes.

Common Signs of the 500 Error in WordPress

You might see:

  • “500 Internal Server Error”
  • “HTTP Error 500”
  • A completely blank page
  • Error appears on admin panelspecific pages, or entire site

Sometimes, this error happens right after:

  • Installing a plugin
  • Updating WordPress
  • Editing theme files
  • Migrating your website

Once you confirm that the problem isn’t caused by the WordPress White Screen of Death the next step is to troubleshoot and fix the 500 Internal Server Error.

Pro Tip!

When dealing with WordPress errors, never apply multiple fixes at once. Make one change, refresh your site, and then move to the next step only if the issue persists.
This approach helps you clearly identify what actually caused the 500 Internal Server Error and prevents creating new problems accidentally.

Why Does WordPress Show a 500 Internal Server Error?

Here are the most common causes, explained simply:

1. Corrupted .htaccess File

This file controls how your server handles requests.
If it breaks, your site can crash instantly.

2. Plugin Conflict

One bad or incompatible plugin can break your entire site.

3. Theme Issues

Faulty code inside your active theme can trigger server errors.

4. PHP Memory Limit Exhausted

Your site may be asking for more memory than the server allows.

5. Corrupted WordPress Core Files

Incomplete updates or failed uploads can damage core files.

How to Fix the WordPress 500 Internal Server Error (Step by Step)?

Now let’s fix these — one safe step at a time.

Step 1: Refresh & Clear Cache (Quick Check)

Before changing anything:

  • Hard refresh your browser (Ctrl + F5)
  • Clear your browser cache
  • Try opening your site in incognito mode

If the error remains, move on.

Step 2: Fix the .htaccess File (Most Common Solution)

This fixes the issue for many users.

How to Do It:

  1. Log in to your hosting control panel or FTP
  2. Go to your site’s root folder
  3. Find .htaccess
  4. Rename it to:
  5. .htaccess-old
  6. Reload your website

If your site loads now – problem solved.

Final Step (Important):

  • Go to WordPress Dashboard → Settings → Permalinks
  • Click Save Changes
    This generates a fresh .htaccess file.

Step 3: Disable All Plugins (Safely)

Plugin conflicts are a top cause of the WordPress 500 Internal Server Error.

If You Can Access Dashboard:

  • Go to Plugins
  • Select all → Deactivate

If You Cannot Access Dashboard:

  1. Open FTP or File Manager
  2. Go to:
  3. wp-content/plugins
  4. Rename the folder to:
  5. plugins-disabled

Reload your site.

  • If it works → a plugin is causing the issue
  • Rename folder back → activate plugins one by one to find the culprit

If your admin area itself isn’t loading, this is similar to issues discussed in our WordPress Admin Not Loading guide.

Step 4: Switch to a Default WordPress Theme

If plugins aren’t the issue, your theme might be.

How:

  1. Go to:
  2. wp-content/themes
  3. Rename your active theme folder
  4. WordPress will auto-switch to a default theme (like Twenty Twenty‑Three)

Reload your site.

If it works:

  • Your theme has faulty code

Update or replace the theme

Step 5: Increase PHP Memory Limit

Low memory can silently crash WordPress.

How to Increase Memory:

  1. Open wp-config.php
  2. Add this line:
define('WP_MEMORY_LIMIT', '256M');
  1. Save & upload the file

Reload your site.

Step 6: Enable Debug Mode (Find the Exact Error)

If nothing worked yet, debugging will show what’s actually breaking.

Enable Debugging:

Add this to wp-config.php:

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

Now check:

wp-content/debug.log

This file reveals:

  • Broken plugin
  • Missing file
  • PHP error line

This step is powerful and often leads to a quick fix.

Step 7: Re Upload WordPress Core Files

If core files are corrupted:

  1. Download fresh WordPress from wordpress.org
  2. Upload:
    • wp-admin
    • wp-includes
  3. Do NOT touch wp-content

This safely repairs WordPress without deleting content.

Pro Tip!

Before editing files like .htaccesswp-config.php, or server settings, create a full website backup.
Even a small typo can break your site, and a backup ensures you can instantly restore everything if something goes wrong.

Step 8: Contact Hosting Support (When Needed)

If the error still persists:

  • Ask hosting support to check server logs
  • They can see issues invisible to users

Sometimes, server misconfigurations cause the 500 error.

How to Prevent WordPress 500 Errors in the Future

  • Always keep backups
  • Avoid nulled plugins/themes
  • Update plugins carefully
  • Use reliable hosting
  • Limit unnecessary plugins

Preventive habits save hours of panic later.
