I did here:
sername and password to edit translations, please change for security reasons,
// this is not your google login/pass, you need to think something new
define('myusername', 'aUSER-NAME');
define('mypassword', '6SOME-PASSWORD');
Obviously with another user and password, is just an example

Then i save, and refresh my website. But not accepting my user and pass.
