Did you restart your server by typing gmx in server console? (or any other equivalent)
If so, don't do it anymore. Just stop&start the server.

// Why don't you simply test foreach like this:

Код:

CMD:hello(playerid, params[]) 
{ 
 new var = 0; 
 foreach(new i : Player) 
 { 
  printf("Iterating\n"); 
  var++; 
 } 
 printf("Result : %d ",var); 
 return 1; 
}

If var == player count, then the issue lies in your code.
