Do you have a registration system in your GM? If yes you have to bypass it, so the NPC's will be able to spawn.

EDIT:

pawn Код:

if(IsPlayerNPC(playerid))return 1;

Anywhere that it is looking for the input such as passwords, login and stuff...

EDIT2: Try

pawn Код:

public OnPlayerConnect(playerid)
{   
       if(IsPlayerNPC(playerid))
    {
        SpawnPlayer(playerid);
    }
}

Edit 3 I didn't see your post Lethal
