Eway Response ID: 00Warning : the secure key is empty, check your payment account before validation

[Gdude]

Hi I'm getting this error in the customer message box of the order email notification -

Eway Response ID: 00Warning : the secure key is empty, check your payment account before validation

 

This only happens if a customer does not leave a message.

The orders are still being processed ok but wondered if there is a fix or if it is alerting to some kind of security risk?

Thanks

 

BTW using 1.4.7.0
