Just today the AusPost calculator has stopped working, giving the error "please enter country code"..
The country code is entered as you can see by the following..
Full Response: charge=0 days=0 err_msg=Please enter Country code.
Now if I copy and paste that exact request line into the rate calculator..
You can see that it gives the response "charge=9.2 days=1 err_msg=OK"
How is it failing?
