Hi!

I have an issue whith automatic email sending. I started to hack the wpsc 3.8.7.1 and the automatic email get broken. I mean, when i puchase something, the email doesn’t work. But if i resend from the wp-admin, it’s working. What files do i have to recheck to find the problem?

Or, how can i resend the email using by php code?
