If you've ever encountered the ERR_CONTENT_DECODING_FAILED error when trying to access your WordPress site, you're not alone. This frustrating issue can prevent you from logging in to your WordPress backend or even viewing your website. Fortunately, there are some steps you can take to troubleshoot and resolve the problem.
In this article, we'll dive into the causes of the ERR_CONTENT_DECODING_FAILED error and provide a step-by-step guide to help you fix it. Whether you're working on a local development environment or trying to access your WordPress site from another PC on your local network, we've got you covered.
Understanding the ERR_CONTENT_DECODING_FAILED Error
The ERR_CONTENT_DECODING_FAILED error typically occurs when the browser is unable to decode the content it receives from the server. This can happen for a variety of reasons, but it's often related to issues with the server configuration or the way the website is set up.
In the context of WordPress, the ERR_CONTENT_DECODING_FAILED error can be particularly frustrating because it can prevent you from accessing the WordPress backend, making it difficult to troubleshoot and fix the problem.
Troubleshooting Steps for ERR_CONTENT_DECODING_FAILED in WordPress
To resolve the ERR_CONTENT_DECODING_FAILED error in WordPress, follow these steps:
1. Check Your Local Development Environment (if applicable)
If you're working on a local development environment, the first step is to ensure that your XAMPP (or similar) server is properly configured. Follow these steps:
- Go to the XAMPP control panel and open the Apache configuration file (httpd.conf).
- Locate the line that says
#Listen 80
and remove the #
to uncomment it.
- Find the line that says
#ServerName localhost:80
and uncomment it.
- Save the changes and restart the Apache server.
Now, try accessing your WordPress site using the local IP address (e.g., http://192.168.1.100/your-wordpress-site
) instead of localhost
. This should help you identify if the issue is related to your local development environment.
2. Check Your WordPress Site's URL Settings
If you're accessing your WordPress site from another PC on your local network, you need to ensure that the site's URL settings are correct. Here's how to do it:
- Log in to your WordPress backend (if possible).
- Go to the "Settings" section and locate the "General" settings.
- Check the "Site Address (URL)" and "WordPress Address (URL)" fields. Make sure they match the correct URL for your site, including the protocol (http:// or https://).
- If the URLs are incorrect, update them and save the changes.
3. Update the wp_options Table
If you're still experiencing the ERR_CONTENT_DECODING_FAILED error, you may need to update the wp_options
table in your WordPress database. Here's how:
- Access your WordPress database using a tool like phpMyAdmin or MySQL Workbench.
- Find the
wp_options
table and locate the rows where the option_name
is home
and siteurl
.
- Update the
option_value
field for both rows to match the correct URL for your WordPress site.
- Save the changes and try accessing your site again.

4. Clear Browser Cache and Cookies
Sometimes, the ERR_CONTENT_DECODING_FAILED error can be caused by cached data in your browser. Try clearing your browser's cache and cookies and then try accessing your WordPress site again.
5. Check for Plugin Conflicts or Coding Errors
If the above steps don't resolve the issue, the problem may be caused by a plugin conflict or a coding error in your WordPress theme or custom code. Try the following:
- Deactivate all your plugins and see if the issue persists. If the error goes away, you know the problem is related to one of your plugins.
- Switch to a default WordPress theme (like Twenty Twenty-One) and see if the error is resolved. If it is, the issue may be related to your custom theme.
- Review any custom code you've added to your WordPress site, such as functions in the
functions.php
file or custom template files. Look for any errors or issues that could be causing the ERR_CONTENT_DECODING_FAILED error.
6. Regenerate Your .htaccess File
Your WordPress site's .htaccess
file can also play a role in the ERR_CONTENT_DECODING_FAILED error. Try regenerating the file by following these steps:
- Log in to your WordPress backend (if possible).
- Go to the "Settings" section and click on the "Permalinks" settings.
- Click the "Save Changes" button to regenerate the
.htaccess
file.
- Try accessing your site again.
7. Deactivate and Reactivate WordPress
As a last resort, you can try deactivating and reactivating your WordPress installation. This will reset your WordPress configuration and may resolve the ERR_CONTENT_DECODING_FAILED error. However, be aware that this will also reset any customizations or changes you've made to your site.
Preventing the ERR_CONTENT_DECODING_FAILED Error in the Future
