pawn Code:

            INI_WriteInt(PlayerAcc,"Cash",GetPlayerMoney(playerid));
            INI_WriteInt(PlayerAcc,"Deaths",0);
            INI_WriteInt(PlayerAcc,"Kills",0);
            SendClientMessage(playerid,ORANGE,"You have just registered, Please use /login [password] to login!");
            PInfo[playerid][Regged] = 1;
            return 1;
        }
    }
    else
    {
        SendClientMessage(playerid,GREY,"USAGE: /register <Password>");
        return 1;
    }
    return 1;
}

The problem is that, it doesn't create a file. No file gets created in my mAdmin/Users.

File must be .ini not .txt

So this

pawn Code:

format(file,sizeof(file),"mAdmin/Users/%s.txt",n);

becomes

pawn Code:

format(file,sizeof(file),"mAdmin/Users/%s.ini",n);

No, still the same

[Zh3r0]

Ah yeah, you need to close the file.

So

pawn Code:

//[...]
            INI_WriteInt(PlayerAcc,"Deaths",0);
            INI_WriteInt(PlayerAcc,"Kills",0);
            INI_Close( PlayerAcc ); //<-- this.
            SendClientMessage(playerid,ORANGE,"You have just registered, Please use /login [password] to login!");
            PInfo[playerid][Regged] = 1;

Oh lol, forgot that. Okay testing.
EDIT: It works, thanks!
