Just to start off, why you use sscanf 2 times? And also sendclientmessage's string should be 128, you don't need to define 3 strings. Just use 1 like i did below.

CMD:warn(playerid,params[]) 
{ 
    if(PlayerInfo[playerid][pAdmin] >= 3) 
    { 

            new Target; 
            new Reason[50]; 
            if(sscanf(params, "us[50]", Target,Reason)) SendClientMessage(playerid, COLOR_LIGHTBLUE, "USAGE: /warn [playerid] [reason]"); 
             if(Target == playerid) return SendClientMessage(playerid, COLOR_RED, "SERVER: Cant perform this command on yourself!" ); 
                if(Target == INVALID_PLAYER_ID) return SendClientMessage(playerid, COLOR_RED, "ERROR: Player is not connected!"); 
                if(PlayerInfo[Target][pAdmin] > PlayerInfo[playerid][pAdmin]) return SendClientMessage(playerid,COLOR_RED,"ERROR: You can't perform this command on Admins that are higher than your level!"); 
                PlayerInfo[Target][Warnings] ++; 
                new tname[MAX_PLAYER_NAME]; 
                GetPlayerName(Target,tname,sizeof(tname)); 
                new pname[MAX_PLAYER_NAME]; 
                GetPlayerName(playerid,pname,sizeof(pname)); 
                new MyString[128]; 
               WarnLog(Target); 
                format(MyString,sizeof MyString, "You have warned %s! (Reason: %s) (Warnings: %d/%d)", tname, Reason, PlayerInfo[Target][Warnings],MAX_WARNINGS); 
                SendClientMessageToAll(COLOR_YELLOW,MyString);
                format(MyString,sizeof(MyString), "Administrator %s has given %s a warning! Reason: %s (Warnings: %d/%d)", pname, tname, Reason,PlayerInfo[Target][Warnings],MAX_WARNINGS); 
                SendClientMessage(Target, COLOR_RED, MyString); 
                if(PlayerInfo[Target][Warnings] == MAX_WARNINGS) 
                { 
                    new name[MAX_PLAYER_NAME]; 
                    GetPlayerName(Target,name,sizeof(name)); 
                    format(MyString,sizeof(MyString),"Player %s (ID:%d) got kicked! (Reason: Maximum warnings)", name, Target); 
                    SendClientMessageToAll(COLOR_RED,MyString); 
                    WarnKick(Target); 
                    Kick(Target); 
                } 

    } 
    else return SendClientMessage(playerid,COLOR_RED,"ERROR: You must be level 3 to perform this command!"); 
    return 1;
}

This should work
