Code:

CMD:unban(playerid,params[])
{
    new string[124],string1[124];
    if(isnull(params)) return SendClientMessage(playerid, red, "/unban [playername]");
    format(string,sizeof(string),"ladmin/users/%s.ini",params);
    if(fexist(string))
    {
					SaveToFile("AdminLog",string);
					dUserSetINT(PlayerName2(playerid)).("banned",0);
    }
    else SendClientMessage(playerid, red, "Account not found");
    return 1;
}

then you will need this code instead of that you have.
