    Why iFrame Shows a Blank Page?

    Asked by moshulu on September 10, 2015 at 08:35 AM

    Hi, the Iframe for one of our forms is not loading on our website, and when tested in Jotform itself I get the same result - it just says "test iframe code" then a blank grey box with a sad face

     

    Thanks

    Harry

    Hi Harry,

    I've confirmed your error and it causes from mixed content. Your form wants to connect with HTTP, but the link of your form choose to use HTTPS secure protocol.

     

    To beat that problem,

    - First, be sure that there is no mixed HTTP, HTTPS link usage together. For instance, you are using HTTP unsecure protocol in your iframe code; but your form's URL uses HTTPS link, you probably will get a blank page.

     

    To change your form's protocol as secure or unsecure,

    - You could follow THIS tutorial to use HTTPS secure protocol.

    - If you don't want to use secure protocol because of the SSL limit, just make sure that "Secure form" check box is not checked.

     

    If you encounter any error, please feel free to ask us.

    Thanks.
