A previously working form has stopped submitting responses.

We've been using this particular form for a few weeks but today the form stopped submitting results. A blank screen is given after the "Submit" button is clicked and no submissions are received. We've created a clone of the form and that works fine.

Apologies for the inconvenience. We have informed our back-end team about this and they have fixed it as immediate as possible. Could you please check again and see if the forms are now working as expected? The problem is isolated in the EU region and it seems to be a server related issue, however, everything should be working now. 

We again apologize for the inconvenience.
