I tried to update my eZpublish from 3.7.2 to 3.7.5, but now when I access to the site like anonimous user I'm not authorized to view any section, the system say me that I'm unauthorized and ask me to login. If I make login with my username and password it works.
Now I have upload again the files of 3.7.2 and my site works again with anonimous users. Sombody has any idea?
