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.
First off, we apologize for any inconveniences caused to you.
The problem seems to have occurred twice to the same person. Can you please ask them the browser they were using when the form/s were submitted?
I have also submitted a ticket to our development team to have this issue investigated. If the cause of the problem is found, we will have this patched soon so that it will not occur again.
In the meantime, we kindly advise you to ask this particular person to re-upload the files.
Thank you for your patience.
Unfortunately, the uploaded file appears to be corrupted causing it to fail to get stored temporarily, causing it to fail to our servers. What you can do is please ask the user to re-upload the file.
If you have other questions, please do let us know.
