Downloading for all publications and sermons has broken. Listening to sermons still works. This is due to an update from the third-party plug-in that organizes both. A support request has been placed. In the mean time, most of this content is still available at the old version of the website.
Update: A work-around has been implemented. The buttons for "PDF" or "listen" are very hard to read at the moment, but it is working again.
Update 2: The buttons are now readable.
