Magento 1.9.1.0 Order Confirmation Emails - Not Sending

Question

I\'ve recently upgraded to Magento CE 1.9.1.0 and our order confirmation emails are not being sent to customers or the employees here that are setup to receive notifications

Answer 1

Just do a small change in order.php (public_html/app/code/core/Mage/Sales/Model/Order.php)

From

$mailer->setQueue($emailQueue)->send();

To

$mailer->send();
