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 are sorry for the inconvenience this may have caused. Unfortunately, we have experienced a temporary issue with the file uploads. However, the issue has been resolved by our backend team and it should be working fine now. I have tried uploading few files on your form and see that they are uploaded normally.
Please check and let us know if you are still experiencing any issue with the file uploads. We will be happy to take a look again.
