“The response is not a valid JSON response”- What happened?
This is one of the popular errors that appear in the Gutenberg editor. The error message “The response is not a valid JSON response” can be caused by numerous reasons. First of all, there are conflicts with plugins or themes installed in WordPress, which can cause errors in the editor. Secondly, Outdated software can also cause this error, because older versions of WordPress, plugins, and themes may not be compatible with the latest version of the Gutenberg editor. Another reason is that corrupted data being sent or received by the editor can cause an error message.
So, how to handle this error? In today’s blog, we will give you some useful solutions to help you get rid of this error. Let’s check the following ways.
How to solve the “The response is not a valid JSON response” error?
Method 1:Deactivate all plugins
As we mentioned above, this error can be caused by any conflicts with plugins in WordPress. Hence, you need to deactivate all plugins to find the plugin causing this error.
Here is a step-by-step tutorial to apply this method:
Go to “Plugins” > “Installed plugins” from your WordPress dashboard to view all the plugins that are currently installed on your website.
Now, let’s deactivate all the installed plugins. You can do this by selecting all the plugins and choosing the “Deactivate” option from the bulk actions drop-down menu.
Refresh the page and check if the error has been resolved. If the error is no longer present, which means that one of the plugins was causing the issue.
Activate the plugins one at a time to identify which plugin is causing the issue. Refresh the page after each plugin activation to check if the error reappears.
Once you have identified the plugin that is causing the issue, you can either look for an update that fixes the compatibility issue or consider finding an alternative plugin that does not conflict with the Gutenberg editor.
If none of the plugins are causing the error, you can try the next methods.
Method 2:Check the URL Settings of the WordPress site
Another prevalent reason for this error is incorrect URL settings. If you enter HTTP instead of HTTPS in your WordPress setting by chance, or there is a mix of HTTP and HTTPS content on a website page, this can cause issues with SSL certificates and lead to this error in WordPress.
To resolve this issue, you can update the URL settings in your WordPress dashboard to use HTTPS instead of HTTP. This can be done by going to the “Settings” menu in your WordPress dashboard, then selecting “General,” and updating the “Site Address” and “WordPress Address” fields to use HTTPS instead of HTTP.
Once you have updated the URL settings, make sure to clear your browser cache and refresh the page to ensure that the changes take effect.

Therefore, a common cause of the “The response is not a valid JSON response” error is a conflict with the permalink structure, which can cause issues with the way that URLs are generated and processed by the editor.

Once you have updated the permalink structure, make sure to save your changes and test the editor to see if the error has been resolved.

After deleting the file from the server. Now, you need to navigate to Settings > Permalinks from your WordPress dashboard.
