if(AdminLevel[playerid] < 1) 
format(string2,sizeof(string2),"{%06x}%s[%d]: {FFFFFF}%s",GetPlayerColor(playerid) >>> 8,pname,playerid,text); 
SendSplitMessageChat(COLOR_WHITE,string2);

If the level is >= 1, it won't format the text so basically "string2" is empty. The SendSplitMessageChat might not check about 0 length and send an empty message. For more than 1 function in a statement, use brackets {}.
