I am using zencart v1.5.0 for my store. Sometime over the past 2 weeks, without me making any changes in admin, I stopped receiving emails confirming when a purchase has been made. The customer also is not receiving a confirmation email.

Under 'configuration' 'email options' I have my email address under 'send copy of order email confirmation to.' And like I said, I haven't made any changes in admin and zencart has been sending order confirmation emails out previously.

I tried just sending an email out from 'tools' 'send email' and that works fine.

Any ideas on how to fix this?

Thanks in advance.
