Order confirmation not being sent

Question

after upgrading from Magento CE 1.9 to 1.9.1 order confirmations not being sent :(. I am using aoe sheduler and I am thinking that's looks fine or not?

But the exception log contains for example after a paypal express order the following:

2015-01-10T08:12:09+00:00 ERR (3): 
exception 'Varien_Exception' with message 'Invalid method Mage_Sales_Model_Order::queueNewOrderEmail(Array
(
)
)' in /home/magento/www/lib/Varien/Object.php:653
Stack trace:

#9 /home/magento/www/index.php(87): Mage::run('', 'store')
#10 {main}

Hope you can help me, because sending order confirmations manually isn't a solution for me.

Assuming you cleared cache, flushed apc/OPcache (if in use), ran compilation process (if in use), here is a small list of things to check:

• Check if all 1.9.1 files have been copies over
• Open app/code/core/Mage/Sales/Model/Order.php and look for queueNewOrderEmail method
• If the method does not exist you don't have latest file
• If the method exists check if some third party module is rewriting the class and check your local code pool for override of the given class
