Spent a whole day on the phone to Adobe 'experts' on Friday and still having the same error message. No one can explain why I can't upload my forms to FormsCentral. They even looked at my form and didn't advise of any error in the setup of the form. I thought perhaps the file name was too long, shortened it but to no avail.
Is there a limit on characters you can set in form fields that I don't know about but should know about? Some of my form fields have been restricted to 17,000x characters.
