As far I know it changed by version 1.6. You can change it in your setup if you add the marriage record to show to visitors – if this is what you want to do (I have done that with my grandparents and since my mum still alive guests normally not able to see marriage record)

If you specifically want that marriage displayed (to clarify Jacolines comment) go to Administration > your family tree > Privacy. Add the family reference and set “show to visitors” to the list of privacy adjustments in the lower half of the screen.
