Solve ERR_EMPTY_RESPONSE WordPress Error Quickly with These 12 Fixes

You’re trying to visit your website, but instead, you come across the ERR_EMPTY_RESPONSE WordPress error. Your site refuses to load, leaving you feeling frustrated.

As the seconds tick by, your anxiety increases. Is this problem affecting all your visitors? Are potential visitors unable to access your site right now? It’s stressful to think you might be losing valuable traffic. 

But there’s no need to worry; we’re here to assist you. This guide will provide simple steps to help you identify and resolve the issue. Let’s get your site back up and running smoothly.

TL;DR: The err_empty_response WordPress error occurs when your server doesn’t send data back to your browser, leaving your site inaccessible. Fix this by checking your internet connection, clearing your cache, and troubleshooting carefully to prevent further issues.

Understanding the ERR_EMPTY_RESPONSE WordPress error

Seeing the ERR_EMPTY_RESPONSE error means your browser reached out to your website, but the server didn’t return anything. 

Normally, when you visit a site, the server sends over all the necessary elements like text and images to display the page. However, with this error, the server remains silent, giving your browser nothing to show.

This situation can be quite puzzling because it feels like reaching a dead end with no clues. It signals a disruption in the communication between your server and browser, typically due to a network or server issue, rather than a problem with the website itself.

Unlike a timeout error, which indicates the server took too long to respond, the ERR_EMPTY_RESPONSE error signifies no response at all. 

The challenging part is that the error doesn’t specify what went wrong. It’s a general alert, similar to the 500 internal server error, which requires further investigation to expose the root cause.

Primary steps to fix the err_empty_response WordPress error

Here are some basic steps to help you resolve the err_empty_response error and get your site back online:

1. Check your internet connection

Start by ensuring your internet connection is stable. A weak or unstable connection can sometimes cause the err_empty_response error. Try accessing your site from another device to determine if the issue is with your network. A reliable connection is vital to resolve this error.

2. Use incognito mode

Open your site in incognito mode. This browsing mode doesn’t save your history or cookies, providing a fresh start. If your site loads in incognito, the problem might be related to cache, extensions, or settings.

3. Clear browser cache and cookies

Clear your cache and cookies. This is to remove outdated or corrupted files that might be causing issues. This step also ensures you’re loading the most recent version of your site.

Tip: You can quickly do this by pressing Ctrl + Shift + Delete on Windows or Command + Shift + Delete on a Mac.

4. Disable browser extensions

Lastly, disable all your browser extensions. These small add-ons can sometimes interfere and cause errors. Click on the three dots at the top right of your screen, go to Extensions, and then Manage Extensions. 

Switch them off. If your site starts working, enable them one by one to identify which extension is causing the problem.

Advanced fixed to solve the ERR_EMPTY_RESPONSE WordPress error

If the basic solutions haven’t resolved the issue, don’t worry—there are more options to try:

Remember, these methods are a bit more complicated than the basic ones. Be sure to follow the instructions carefully and take your time.

1. Reset network settings

Resetting your network settings can sometimes resolve the problem, especially if there are IP or DNS issues involved.

On Windows, open the Command prompt and enter these commands one by one:

netsh int ip reset

ipconfig /release

ipconfig /renew

ipconfig /flushdns

On a Mac, open Terminal and type:

sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder

2. Flush your DNS cache

Clearing your DNS cache can help if outdated IP addresses are causing issues.

On Windows, open the Command prompt and type:

ipconfig /flushdns

On a Mac, use Terminal and type:

sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder

3. Disable Plugins via FTP

If you suspect plugins are causing the problem, access your WordPress files using FTP. Navigate to the /wp-content/plugins/ folder and rename it to something like plugins_dis.

Check your site to see if it works now. If it does, plugins are likely the cause. Rename each plugin folder individually to deactivate them, and then reactivate them one by one while checking your site to find the problematic plugin.

4. Revert to a default WordPress theme

Your current theme might be causing the issue. Try switching to a basic theme like Twenty Twenty-One using FTP. Access your WordPress files via FTP, go to the /wp-content/themes/ directory, and temporarily rename your current theme folder. 

This will cause WordPress to revert to a default theme, which can help you determine if your theme is the problem and fix it.

5. Increase PHP memory limit

If your site needs more memory to run smoothly, increase the memory limit by adding this line to your wp-config.php file:

define('WP_MEMORY_LIMIT', '256M'); 

This gives your site more room to handle data.

6. Verify database connection

Ensure your database credentials are correct. Check the wp-config.php file for lines such as:

define(‘DB_NAME’, ‘database_name_here’);

define(‘DB_USER’, ‘username_here’);

define(‘DB_PASSWORD’, ‘password_here’);

define(‘DB_HOST’, ‘localhost’);

7. Check firewall and security settings

Make sure your firewall and security software are not blocking important data. Verify that they allow access to your site.

8. Contact your web host provider for assistance

If nothing else works, reach out to your web host provider. They can help with server issues and offer insights to solve the problem.
