We are helping a client with some issues - we didn't build the site originally and don't really have any experience with using or setting up Hotcakes. So we aren't sure where to start troubleshooting this issue. The site is http://www.campusfiresafety.org/.

They had the setting of "use email as username" turned on and were having issues with users not being able to reset their password. So we enabled the "require unique email address" setting to fix that problem.

However, now they are seeing an issue in the cart/checkout where it won't create new users. They get a message saying the email is already associated with an account - even though it's not in the system at all.

Do you know of a quick fix for this? It's in Version - 1.10.3 Pro.
