Page Content Translation does not work

Hi,
I have a problem with the translation of the Page content message: Sorry you have no rights to view this page!

I am using WPML to manage the translations and it finds correctly the strings in the String Translation Module. Though, when browsing my site, the first sentence does not translate. The login form translates smoothly.

Furthermore, the plugin is not translated in my dashboard. My website is in Italian and English.

You can see and example here http://pin.cecilialessandrini.it/en/press-area/.

Anyone can help?

Thanks
