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.
Free accounts are allowed up to 10 submissions with payments per month. It looks like you may have reached that limit. Once your form goes over its limits, your users are presented with the "over quota" error, instead of the form accepting the submission.
Since you have already upgraded your account, I assume you knew this already. You should no longer be having any issues with the "over quota" error and you are now well below your account limits.
If you have any further problems with that error or any questions in general, let us know and we will be happy to help.
