This form is disabled upon sumission

Additionally, some of our applicants have written us this morning stating upon hitting submit, found that the "Form has been disabled". Is there any guidance you can provide in addition to the iFrame suggestion? 

Hi,

I checked your form and your account and both seem to be in order.  Usually that message only occurs if you have set a submission limit on your form but I had a look and this is not the case:

Your account is well under its submission limits so your form would not be disabled for this reason either.  I checked our admin logs and there was not activity so your account hasn't been disabled by us for any reason.  As far as I can tell your form should be 100% working.
