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.
I see that your account is currently having a total of 454 submissions. Please be noted that the Free subscription accounts are limited to store only 500 submissions and so you have received the notification. I notice that you have already tried exporting the form data and the file created is not working. It seems that there is an issue with creating the compressed file using the form data.
Let me forward the issue to our backend team to take a look. Once we have any update in this regard, you'll be posted here.
