It's the same thing when i replace by another text.

Hi but you remove only 'Black&White' or all line ?

This is actually code in my folder :

BACK TO TOP=Back to Top
TOP=Top
MOBILE VERSION=Mobile Version
DESKTOP VERSION=Desktop Version
SWITCH TO STANDARD MODE CONFIRMATION=Switch to standard mode? Switch back to mobile view via a link at the bottom of the page in standard mode
DO NOT SHOW THIS MESSAGE AGAIN=Do not show this message again
CLOSE THIS NOTICE=Close this notice
GK_LOGIN=Login
GK_ACCOUNT=Your account
GK_REGISTER=Register
NAME=Name
VERIFY_PASSWORD=Verify password
REGISTER_REQUIRED=* Field is required
IE6_BAR=Internet Explorer cannot render properly this page. Please click to read more...

Ok, you deleted all line, it was unnecessary. Add this to the top:
YOUAH=
In this way you define YOUAH as empty char and nothing shows up.
