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.
We would like to recommend checking a Form Revision history tool. If updated form was saved properly, there is a chance that you can restore it to the previous version.
Additionally, forms saves are supposed to be listed on a history page.
Also when you edit the form, make sure to use only one browser tab with edited form to avoid incorrect autosaves. You can also use a Save icon to save the form from time to time.
Please let us know if you need any further assistance. We will be happy to help.
