[doankhoavy]

Hi All,

I'm new OTRS,

I don't know how to translate text message in the Kernel\System\Web\InterfaceAgent.pm

for example

# show logout screen
$LayoutObject->Print(
Output => \$LayoutObject->Login(
Title => 'Logout',
Message => 'Logout successful. Thank you for using OTRS!',
%Param,
),
);

I want to translate message 'Logout successful. Thank you for using OTRS!'

I put 'Logout successful. Thank you for using HelpDesk!'=> 'abc ..................', the the my language file but it not work for me

Please help me.
