I am trying to tweak some settings based on some user input. So i am searching for a text string "New? Please Provide Your Billing Address". No matter which input/search group I use in the developer's tool kit, I get

Code:
Error: No matching Configuration Keys were found ... New? Please Provide Your Billing Address
This is happening on both my production site, v2.0.1 and on my dev site which is v2.1.0.

First off, I expected to find the location of the string. It displays on my website so I know it there ...somewhere. I have been searching all files in both admin and catalog.

Secondly, I do not understand why there is an error...
