    After updating the plugin, an error appeared when saving an entry or page, an error appears.
    Update error. The response is not a valid response in JSON format.

    this situation has developed on two sites after the update
    By disabling all plugins and enabling it, I discovered that it is Yoast SEO that causes it.

  • Hello @midas34 ,

    It’s seems Invalid JSON response” after Yoast update = PHP error breaking REST API or output buffer conflict.

    You can enable debug and check any Yoast PHP errors after trying to save.

    You may wait more for official reply.
