JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
If I understand you correctly, you are receiving this error on the website where you have embedded the form - and not on JotForm when you are editing your form.
Could you please let us know the link to the page where you have embedded your form, so that we can check and see what seems to be the issue?
We will await your response, thank you.
