I have Plone 4.0.2 setup with LinguaPlone 4.0.1 and all of my pages (including "Home", "About", "Contact", etc.) translated into French and Spanish (English as default). I get the three languages available in the top-right corner of the screen and when I click on any other language, the site and all page contents are translated properly (including the navigation tabs, so "Home" becomes "Accueil" in French, and "Inicio" in Spanish).
The problem is when I am browsing the site as a different language and click on "Home" (or "Accueil"/"Inicio"), the home page displays in English. Yet everything else is still in that other language (French/Spanish). I have to re-click the language I want to view the homepage as before it is displayed in that language.
The home page is the only page that this doesn't work on. I can navigate to any other part of the site in French or Spanish and everything but the Home page displays properly. Is there some strange setting I'm missing for the home/default page?
See my answer on How can I add translations to a Plone site front-page; you need to run the LinguaPlone setup:
