I think I know a solution for this, I think you forgot something its showin' below:

pawn Code:

public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
    print("[OnPlayerKeyStateChange]: newkeys: %d oldkeys: %d,newkeys,oldkeys);
        return 1;
}

Just copy that PAWN code.

and it is not like this

pawn Code:

printf("[OnPlayerKeyStateChange]: newkeys: %d oldkeys: %d",newkeys,oldkeys);
