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 did not see any complete submissions. Your most recent form shows as being deleted. If you would like to restore that form, it should still be in your trash:
I tested your form that was not deleted and the file uploads to appear to be working.
If you still receive a 404 error for your file uploads, let us know and we will be happy to have another look.
