Do i need a SSL host to make WPBOOK work with my WP site, facebook page and facebook app?
Even tough i put http:// on canvas page in the fb app and save i get https://
FB displays something about secure urls required from october 1st.
I can see the content when typing, http://apps.facebook.com/posta-till-fb in browser. But when i try to view it from my fb page tab i get a blank page.

Yes, SSL is required for WPBook.
Or, more accurately, constructing a Facebook application is required for WPBook and Facebook now (since Oct. 2011) requires that all Facebook applications exposing a canvas page or page tab view provide an SSL version of their urls, and it has to be functional.
