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.
I see that all the existing forms are whitelisted in your account and you shouldn't be having any issue with the forms. Please let us know if you continue to see this errors. We will be happy to look into this.
