Updating failed. The response is not a valid JSON response.

  • I keep getting this error when I try to save changes on any pages, plus I cannot get access to my media library. I went through some old forum posts, but I’m not really sure what to do to resolve this issue.

    This may be a plugin or theme conflict. Please attempt to disable all plugins, and switch to the default Twenty Twenty-One theme. If the problem goes away, enable them one by one to identify the source of the problem.

    If you can install plugins, install Health Check. On the troubleshooting tab, you can click the button to disable all plugins and change the theme for you, while you’re still logged in, without affecting normal visitors to your site.

    Did you install a plugin lately? Or did you upgrade WordPress?
