Aiuto per Autoboss

Mi hanno passato questo script per il sito che stò tentando di realizzare. Dopo che apro il file di setup e inserisco tutti i dati riguardo il Database Host, viene fuori questa pagina:

non riesco a capire cosa devo correggere per farlo funzionare...!
Ho provato a cambiare i permessi di scrittura con Filezilla, "cambia gli attributi del file", quando lo apro ci sono tre X,
cambiandole con 777 quando lo riapro ci sono di nuovo le X. Come mai non memorizza il cambiamento? se apro il file (admin/cp-includes/inc-confdata.php) la pagina e vuota, non cè scritto nessun codice.
Riporto le uniche tre stringhe dove cè il comando fopen nel file setup.php

192 $fp = fopen ($confdata, 'w');
236 $fp = fopen ($confdata, 'a');
252 $fp = fopen ($confdata, 'a');

non mi sembrano protette
w Per sola scrittura (I dati già scritti andranno persi e se il file non esiste sarà creato).
a Per aggiungere (I dati saranno aggiunti in coda a quelli già scritti, se il file non esiste sarà creato.)
Spero ci sia qualche anima pia che mi possa aiutare.
Grazie in anticipo
