Problema con edit-listing.php di esyndicat

Ciao a tutti,
ho un problema con il file edit-listing.php del cms per directory esyndicat 1.6. Ho pensato che questa fosse la sezione più adeguata perchè il problema non è il cms ma questo specifico file.
In pratica il file edit-listing.php è quello deputato alla modifica delle inserzioni già esistenti. Il problema è che quando provo a modificare l'inserzione cliccando su salva, come risposta ottengo una pagina bianca e nessuna modifica viene salvata.
Ecco di seguito il codice, secondo voi c'è qualcosa da sistemare?

Nel forum di Esyndicat un utente dice inoltre di aver risolto il problema così:

Ho risolto in un modo non troppo corretto, ma comunque funzionante.

In /admin/edit-listing.php ho commentato la linea 78:
PHP Code:
$temp['alias'] = utf8_to_ascii($temp['alias']);

Chi mi dà una mano? Grazie.

[fortunecat]

Ho scoperto che la tipologia di errore è questa:
**```
Cannot modify header information ? headers already sent

Non c'è proprio nessuno che sappia spiegarmi cos'ha di sbagliato il codice? Ho capito che prima di header() non ci deve essere nessun tipo di output ma qui non vedo nulla di strano...
:?

EDIT: Risolto. Grazie lo stesso. :)
