blank screen and no notifications

All of our forms are not sending email notifications or confirmations. All of the payments go through but nobody knows about it.

Once you have this issue resolved, can you confirm that it will email any form data/transactions on all of our forms while it was broken? Customer's need receipts and we need confirmations. 

Hello DrivePayments,

I can't seem to find any failed email deliveries of your email alerts. Can you tell us which email address you've used and is not receiving an email? Also, have you checked your junk mail folder for possibilities that the emails landed there?

Thanks.
