rename all instances of str in my code to strtemp,

pawn Код:

new Player[MAX_PLAYER_NAME],strtemp[128];
    GetPlayerName(playerid, Player, sizeof(Player) );
    format(strtemp,sizeof(strtemp),"%s has teleported to /LSA", Player);
    SendClientMessageToAll(COLOR,strtemp);

I also recommend not using things such as STR on a global level as they usually indicate a temporary string not important enough to be named.
