At first: you forgot the return and the clsoing bracket...
Then try this:

pawn Код:

public OnPlayerDisconnect(playerid, reason)
{
        new pname[MAX_PLAYERS],accFormat[128];
    GetPlayerName(playerid,pname,sizeof pname);
    format(accFormat,sizeof accFormat,"/Players/%s.datei",pname);
    if(fexist(accFormat) && Spieler[playerid][eingeloggt] == true) // or == 1
    {
    dini_IntSet(accFormat,"skin",Spieler[playerid][skin]);
    dini_IntSet(accFormat,"Score",GetPlayerScore(playerid));
    dini_IntSet(accFormat, "AdminLevel", Spieler[playerid][AdminLevel]);
    dini_IntSet(accFormat,"Mute",Spieler[playerid][Mute]);
    dini_IntSet(accFormat,"gebannte",Spieler[playerid][gebannte]);
    dini_IntSet(accFormat,"gekickte",Spieler[playerid][gekickte]);
    dini_IntSet(accFormat,"vip",Spieler[playerid][vip]);
    }
        return 1;
}
