If I understand you correctly, you're saying that the form is not appearing in the Facebook page. Do you see any error on the screen when you click the tab?
Please try to remove the JotForm tab in the Settings > Apps section. After that, log out from Facebook. Go to JotForm and try adding the form again to your Facebook page using this guide: https://www.jotform.com/help/22-Adding-a-Form-to-Your-Facebook-Page.
Please provide the URL of your Facebook page so that we can further check.
Hope that helps. Let us know if the issue is still the same. Thank you.
