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 checked your form and it appears to be available. There are no limits set for submissions, it is set to enabled and your account is below its limits. Is it only this one person who is unable to use the form? I checked a few of your other forms to make sure there were no issues and they all appear to be active and usable.
