    Error: Invalid Form URL

    Asked by marellmediasystems on October 24, 2013 at 02:41 AM

    When previewing my form I get a message "illegal URL". What's wrong? Are your servers down?

    Hello marellmediasystems,

    Upon checking the contact page of your website, I found it to be working fine. I even sent you a test submission successfully. 

    Are you seeing the error when you click on preview button of form editor? Do let us know which domain you are using to login to your JotForm account? The JotForm domain assigned to your form seems to be http://www.jotformeu.com. Please login using this domain and see if the still get any error.

    DO get back to us if the issue persists.

    Thank you!
