you're using playerid, instead of i.

Код:

stock SendMessageToAdmins(text[])
{
    for(new i = 0; i < MAX_PLAYERS; i++)
    {
        if(pInfo[i][Admin] >= 1)
        {
            SendClientMessage(i, -1, text);
        }
    }
}

P.S. IsPlayerAdmin <-- function, detects only RCON logined users as admin.
