Hello,

IIS 6
PHP 5.2.1
ZenCart 1.3.7

When a new customer signs up or someone uses the Contact Us form this error is thrown.

Code:
Email Error: Could not instantiate mail function
This just started occurring and I have not made any changes to the store or the server. My SMTP is running, messages are going through, and the PHP function works just fine when used outside of ZenCart.

What exactly triggers this flag?

Thank you,

TheMusician
