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 have tried cloning your JotForm to my account. When I tried saving the form, it saved without any issue at my end.
Please try logging out from your JotForm account and try logging again to see if that works. You may also try opening the form in a private window or a separate browser and see if you are able to save the form normally.
Please get back to us if you need any further assistance. We will be happy to assist.
