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.
It should not be neccesary to clear your browser's cache everytime you access your form's submissions (presumably from your submissions page).
I have tested the form http://www.jotformpro.com/form/40043319196956, which currently contains 9 submissions. But I was not able to replicate the problem. Still we need to find out what is causing this on your end.
Have you tried to access your account from a different workstation?
