JSON response not valid

  • Hello,

    I am editing an element (will be a template for a specific page of my website) using post metas and headlines blocks. Everything is based as usual on ACF.

    The thing is that I am repetetively getting the error you see in the image attached.

    Can you please help me?

    Link in private information.

  • Hi there,

    do you have either:

    a) a shortcode on that page
    b) any functions that affect how a block is displayed

    Let me know

  • this website is installed on a custom server, could it be a firewall issue?

  • It could be, firewalls or security settings can block the server response. Unfortunately WP is very lack lustre with that error notice.

    If you check the server error_log or the browser developer tools console when the error appears, it may provide some more info.
