to solve the Unknown Command just add a return true

pawn Код:

if (strcmp("/admins", cmdtext, true) == 0)
    {
        new string[128]; //Tip: read the topic about string length by ******
        for(new i; i < MAX_PLAYERS; i++) //you dont need to declare i as 0 because all values in pawn are at creating 0
        {
            if(IsPlayerConnected(i))
            {
                if(Level[i] == 1)
                {
                    if(!string[0]) SendClientMessage(playerid, COLOR_WHITE, "========== Admins On‌line ==========");
                    GetPlayerName(i, string, MAX_PLAYER_NAME);
                    format(string, sizeof string, "Administrator: %s", string);
                    SendClientMessage(playerid, COLOR_WHITE, string);
                }
            }
        }
        return true; //if you return false (that happens when you dont put a return at the end of a command) the text Unknown Command will appear
    }
