I have a problem with photo-albums switching back to the primary language.
Take a look at http://www.giavandenakker.com/?page_id=123&wppa-album=4&wppa-cover=0&wppa-occur=1
This page displays an album with only two daughter-albums. I can change the language for this page, but when I choose an album to display, the language switches back to dutch, as can be seen in the breadcrumbs and the photo-titles. Then only after pressing F5 things change to the right language.
