TOPIC: Sorry! The donor's details could not be stored in database.

After submitting a donation, I get this error:
Sorry! The donor's details could not be stored in database.

Everything goes to Authorize.net fine, but nothing goes into the site's database.

I'm using the latest version of DtDonate - Just upgraded today and still have the same issue.

I put in a support ticket but haven't heard back. Hoping maybe someone else has experienced this problem and has the solution.

Thanks!
