You overwrite fstring.

PHP код:

CMD:admins(playerid, params[])
{
    new string[512] = ""COL_GREEN"Online Administrators:\n\n"COL_WHITE"", fstring[256] = ""COL_GREEN"Online Very Important Players:\n\n"COL_WHITE"";
    foreach(Player, i) //foreach(new i : Player)
    {
        if(PlayerInfo[i][AdminLevel] > 0) format(string, sizeof(string), "%s^ %s(%i) (Admin Level %d)\n", string, PlayerName(i), i, PlayerInfo[i][AdminLevel]);
        if(PlayerInfo[i][VIP]) format(fstring, sizeof(fstring), "%s^ %s(%i)\n", fstring, PlayerName(i), i);
    }
    strcat(string, fstring);
    ShowPlayerDialog(playerid, DIALOG_ADMINS, DIALOG_STYLE_MSGBOX, ""COL_GREEN"UGF - Online Admins / Vips", string, "OK", "");
    return 1;
}
