Understanding the “Updating Failed. The Response is Not a Valid JSON Response” Error
“Updating Failed. The Response is Not a Valid JSON Response” is a common error in WordPress encountered when you try to save changes to a page, post, or any other site content. This error signifies that there is an issue with communication between your website and the server.
This error frequently arises due to conflicts with the themes, plugins, or even your server configuration. It is quite frustrating, as it prevents you from updating your site or making any changes to your content. To fix it, you can try following troubleshooting steps:
- Check for Theme or Plugin Conflicts – Deactivate all your plugins and switch to the default WordPress theme like Twenty Twenty-One to see if the error persists. If the problem goes away, you can find out what causing it by reactivating each plugin and theme one by one until the problem comes back. This will help you find which plugin or theme causing the issue.
- Increase PHP Memory Limit – Sometimes this JASON error occurs due to insufficient memory limit. You can increase the memory limit by adding the following code to your wp-config.php file – define(‘WP_MEMORY_LIMIT’, ‘256M’); this code will increase the limit to 256 megabytes.
- Check your WordPress Site Address Setting – If the site settings of your WordPress dashboard are incorrect, the editor will not be able to communicate with the server. To check this, go to Settings> General and make sure that the site address (URL) and WordPress address (URL) fields are correct.
- Fix your WordPress permalink structure – If your WordPress permalink is not configured correctly, it can also cause this error. To fix your permalink structure, go to Settings > Permalinks and select a permalink structure that works for you. Then, click Save Changes.
- Regenerate your WordPress .htaccess file – If you’ve set up a custom permalink structure, you might have to recreate the .htaccess file for WordPress. To do this, go to Settings > Permalinks and click the Save Changes button. WordPress will automatically regenerate the .htaccess file.
- Disable Security Plugins or Firewall – If you are using any security plugin or firewall, consider disabling it temporarily. It is possible that they could be stopping the JASON response. If this solves the issue, you can adjust the security plugin or firewall setting to allow the JASIN response.
- Update WordPress Core, Plugins, and Themes – Sometimes, when your WordPress, plugins, and themes are not updated to the latest version they can create problems that result in an “Updating Failed” error. To prevent such conflict, make sure your WordPress, plugins, and themes are updated with the latest version.
- Check your site health – Go to Tools > Site Health and click the Status tab. Scan your site for any issues that could be causing the error. If any problems are found, WordPress will provide recommendations on how to fix them.
