    500 Internal Server Error caused by the upload field

    Asked by outofstepbooks on January 01, 2015 at 04:53 PM

    I received notice from someone trying to use our form and I have duplicated the issue on my computer as well.

    When submitting it is either timing out or getting a 500 Internal Server Error. I have gotten the form to go through twice out of about 15 tries and I did not receive an email on either of them. The other 13 tries just gave the error.

    The form is located at


    Nothing has changed on the form since before when the form was working fine.

    Any help would be appreciated.

    Thanks, the problem is not the form showing up. The image I attached is what you see once the form is submitted.

    Sorry if I did not explain it correctly. The issue is when you fill out the form you either get the server error OR it does submit and shows the thank you page. 

    If it does submit and shows the thank you page we do not get the notification email (we have never had a problem with our notifications until the error started). On top of not getting the notification email if I go to the jotform site and look at my submissions on there I can see the submission, however, the image is not there. 

    On the submission page it just shows a small blue square with a question mark in it. 

    I duplicated the form and the duplicate form works fine. The old form worked yesterday but not today.

    Yes, we have found out that forms rendered on jotform.us domain are having problems with uploading files.

    I see your new form is rendered on jotformpro.com which is a working one. So, seems like by cloning the form the issue was fixed? Please do let us know should the issue persists on your end.

    The upload field is the one causing the error - users could not upload files due to a full hard-disk. 

    We have since resolved the issue, and your form should work normally now. 

    I tested it, but kindly check and let us know.
