When create a order mail not received Admin only received by user for order.. i try to change cron setting but not working yet..please give me answer is that default magento problem?
When I upgraded my website to 1.9 version, I also faced the same problem where Order emails were not going.
There has been a change in the way emails are sent in 1.9.x version. After debugging on my deployment, I saw the error was related to mb_convert_encoding (lib/Pelago/Emogrifier.php) was not defined and the method was not returning.
I installed php-mbstring and the issue was fixed. I used the following command to install php-mbstring
yum install php54-mbstring
