Users receiving "Form is currently unavailable!" when form is enabled.

Hello,

Today is the final day of a call for submissions we are doing. The form has been open for two months with no problems.

Last night the form disabled itself with no warning. This morning when I re-enabled it, the form is having a number of issues... users can see the form, but when they hit submit they are seeing the "This form is currently unavailable!" sign even though the form is enabled.

I have refreshed the embed code on the webpage where the form lives. One submission came through and then another user told me they ran into the same problem.

Is there something else I can do? It is vital that this form works seamlessly today!

I'm unable to reproduce the issue. I just made some test and I was able to submit your Jotform without any errors. It takes some time to submit since you have upload fields for PDF and images.

Here's  my test
