    Hi Xin and greetings for you!

    I hope this helps you a little bit

    I have had the same problem before. I used the FB developer method and was working fine.

    But the problem began when I changed the fanpage to the new FB layout , which doesn't allow me to create applications or manage tabs the way it was before .

     So apparently it seems to be a bug in FB regarding to this new layout . As it was working before, like yours .

    I am planning to contact FB support in order to have further information.

    Hi Xin,

    What code app are you using to read your jotform codes? Is it a custom one or 3rd party? This could be an app issue. (due to the recent fb update)

    Have you tried these options below?


    Adding Forms to Facebook (Static HTML App Method)


    Adding forms to Facebook ( Facebook Developer Method )

    Hope this helps.

    You may be using an old method to embed the form into your Facebook page, as one of the Facebook Embed Guide is already deprecated. Please check this step by step instruction on how to reinstall the form on your Facebook page and let me know if it works.



    Hope that helps :)
