after updating to 22.214.171.124 the customer and I get no order mails anymore.
Cronjob is running fine (checked with AOE Scheduler).
Table core_email_queue exists but is always empty.
Manually sending mail from within the order works.
what are you using for smtp? we were using smtp pro and just set the settings in configuration to "never" go through the cron que. works perfectly nlw.
OK, I found the solution.
There was a left over from before the update: /app/code/local/Mage/Sales/Model/Order.php
After deleting this file everything is running fine again.
But thanks anyway!
Renamed the folder Mage to Mage.bak and it solved my problem.
The mage folder was still an old magento folder. I think it overwites the new core files.
