Problems with WP 3.9

Hello,
I updated to 3.9
The problem is for articles.
i.e.
http://www.vinilificio.com/wordpress/?portfolio=stampa-vinili-neri-e-colorati

No content. If I go to the admin of the article I can manage the contents. But on the link nothing

Pages actually seem to be ok :
http://www.vinilificio.com/wordpress/?page_id=524

Any suggestions?
I have the back up of the database and everything.

Thank you,

Cristian
