I'm a newbie so apologies in advance. I have setup the e-commerce module [v0.5.2] and everything seems ok except I am not getting the emails sent out to the customer and shop. I have tried setting this in both the ecommerce config.php and the mysite config.php using

// Set the email of the admin who looks after receiving the order emails.
Order::set_email('llewetest@gmail.com');

I have also set the admin email in mysite config.php using

Email::setAdminEmail('llewetest@gmail.com')

and this works, sending me two emails saying that "A message that you sent contained no recipient addresses"

Why is it not picking up the email addresses? Am I setting this in the wrong place?

Hi, this is pretty old now but I had the same problem. It turned out to be a misordering of a parent constructor. Anyway the fix for me went like this:
ecommerce>order.php line 1195 (roughly)

class Order_receiptEmail extends Email {

	/*private static $StoreName = "Shop Sale";
	public function setStoreName($name){ $self->StoreName=$name; }
	public function getStoreName(){ return $self->StoreName; }*/
	
	protected $ss_template = 'Order_receiptEmail';
	
	public function __construct($to = null, $from = null, $subject = null) {
		parent::__construct();
		$this->to = $to ? $to : '$Member.Email';
		
		$this->from = $from;
		$this->subject = $subject ? $subject : '$StoreName reference (#$ID)';
				
		if(!isset($this->from, $this->subject)) {
			user_error('From or subject for email have not been defined. You probably haven\'t called Order::set_email() in your _config.php file.', E_USER_ERROR);
		}
		
		
	}
} 

this is the fixed version. all i did was move the line

parent::__construct();

to the beginning of the function.
Hope this helps ;)

thanks so much - this does work!
