A user filled in a form, and saved.
They received the email with the save link; they can get back to the form with the link that was sent,
but clicking the submit button returns a server error. I have obtained the link from the user, and I get the same error.
The form contains sensitive data (employment application).
An error has occurred.
There was an error communicating with the server. Please try again later.

Test form doesn't display same problem.
