Well, you have added the defines for the commands in DCMD, but you did not add the commands itself yet, so that won't work.

Also, this

pawn Код:

if(gPlayerInfo[playerid][PLAYER_REGGED] == 1)
        return SendClientMessage(playerid, COLOUR_ORANGE, "ERROR: You have already registered!");
    else if(!params[0])
        return SendClientMessage(playerid, COLOUR_ORANGE, "USAGE: /register [password]");
    else if(strlen(params) < gSettings[PASS_MIN] || strlen(params) > gSettings[PASS_MAX])
    {
        new string[128];
        format(string, sizeof(string), "ERROR: Password must be between %d and %d characters long!", gSettings[PASS_MIN], gSettings[PASS_MAX]);
        return SendClientMessage(playerid, COLOUR_ORANGE, string);
    }
    else
    {
        new password = num_hash(params);
        gPlayerInfo[playerid][PLAYER_PASS] = password;
        gPlayerInfo[playerid][PLAYER_REGGED] = 1;
    gPlayerInfo[playerid][PLAYER_LOGGED] = 1;
        GetPlayerIp(playerid, gPlayerInfo[playerid][PLAYER_IP], 16);
        new string[128]; format(string, sizeof(string), "You have successfully registered your account with the password \'%s\'. You have been automatically logged in.", params);
        return SendClientMessage(playerid, COLOUR_LIGHTBLUE, string);
    }

Won't work as you did not put it in a command, it's just floating somewhere in OnPlayerCommandText.

To fix them, just add the commands and put that code ^ in a command.

Edit: also remove

pawn Код:

return 0;

From under the DCMD stuff. You should learn scripting before trying such things
