What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
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.
As said on this other duplicated thread you opened https://www.jotform.com/answers/1043718. It means you have reached your submissions limit; however, I have checked your account and found you're a sub-user account, the form you mentioned is under a different account and it is under the bronze plan, the limits seem to be fine and the form works fine as well, please check and let us know if you have any question.
