Why form is not appearing on WordPress website?

O formulario de contato não aparece no wordpress, o que faço?

As suggested on the other thread, you could get the iFrame code of your form to avoid conflicts between the form's code and the webpage's code. 

Here's the guide: https://www.jotform.com/help/148-Getting-the-form-iFrame-code 

If this does not work for you, please share us the link where you've embedded your form, we will be glad to further check it. 

Looking forward to your response.
