Both, logged in as Revisor, if I create a page and safe as draft, no preview. If I revise a page and put it into the revision queue, I can’t see a preview in the “editing window” or from the drop down menu under the page name within the Revision Queue. Only thing I get is 404 Page Not found errors –
Oh no! That page can’t be found.
It looks like nothing was found at this location. Maybe try using the search?
