tank_auth config file not loading

[eluser]zulubanslee[/eluser]
I want to use a username and not just an email for user logins, but on the register_form.php page I get the error

Code:

Message: Undefined variable: use_username
Message: Undefined variable: captcha_registration

I can confirm that these are set as TRUE in the config file included in the setup, and when I do a var_dump on $use_username it comes up as NULL.

Obviously the config file is not loading, the question is "why"?

Any thoughts on what to check for?

The view is embedded inside another view, if that matters. The form looks good otherwise.

Did you drop the config file into the config folder?

Yes I did.
