form unavailable

I cloned an expired form but the new form does not have an expiration date. When people fill out the form and submit it, the error displays that the form is not available. How can I fix this?

Hi,

I checked your form and there were several submissions from today.  Is everything now working?  If not, let us know and we can send some test submissions through your form.  As far as I can tell though, you form should be accepting submissions.
