You probably got something conflicting with SendClientMessageToAll but there is a way around it such as loop around all the players

Код:

for(new i = 0; i < MAX_PLAYERS; i++)
    {
        if(!IsPlayerConnected(i)) continue;
        SendClientMessage(i, 0x33AA33AA, "Someone spawned!");
    }

EDIT: I didn't see the typing error either but this would be a alternative.
