Errore nel LOGOUT

[tavolez]

Ciao ragazzi, io ho un problemino che sembra irrisolvibile.
Ho installato sul mio sito il forum SMF RC1 seguendo passo per passo la guida di Kenton in sezione forum.

Pero' da quando ho installato questo forum mi accade una cosa strana:

Ogni tanto quando faccio il LOGOUT dal mio sito mi si presenta una pagina bianca di errore dove c'e' scritta ripetutamente la mia username e la mia password. Se faccio un REFRESH torna tutto a posto e vengo di nuovo riindirizzato alla homepage del mio sito dove posso effettuare il logout e questa volta funziona tutto perfettamente.

vi do una mano, questa è la schermata di errore che mi si presenta quando faccio LOGOUT al sito, pero' cio' sembra avvenire solo quando faccio il LOGOUT dopo che le informazioni nel mio browser non sono piu' memorizzate (ad esempio dopo qualche ora che non accedo al sito).

Ragazzi proprio nessuno ha questo problema?

Addirittura ora che ho cambiato di dominio al sito quando faccio il LOGIN e il LOGOUT vengo reindirizzato a una pagina bianca e sono costretto a tornare alla pagina precedente col browser
