Just Download the "MiscHandler.cpp" & put it in your Source Folder ...src\server\game\Handlers

Copy the Code & replace it at line 398 in "MiscHandler.cpp".*

Remove the line 398 by Pasting the code on it

Code to Paste On line 398

std::string playerName = ""; //temp storage

//definition of playerName depending on the (player/GM)'s rank
if (target.GetSecurity() >= 1) //if the rank is 1 or above
    playerName = "|cffFFFFFF[|r|cffFA8258Staff|cffffffff]|r  " + target.GetPlayerName();
else
    playerName = target.GetPlayerName();

//data << target.GetPlayerName();                 // player name - commented out to be replaced with the new playerName
data << playerName;                               //player name - with Staff indicator
