Track Package from FedEx, UPS, Postal, DHL, etc..

I can only suggest first checking your store's orders.php against the one in the 3.1 fileset and make sure that all the required modifications are in place in yours..

Diva,

All files are installed correctly, I think, and I have a situation here.

If I update order with writing something in Comments, then sent emails will carry tracking number, if I leave Comments in blank, then sent email won't carry any tracking number.
