Hi,
if you create a page via “content +” (and not as usually via wordpress > pages > new) and then specify a parent, the parent page is missing in the URL for “view in frontend”. Is this possibly due to some basic settings?
By the way: I have been testing the new version for a few days on a fresh and clean test site. There are generally still some bugs in the workflow in there, I wouldn’t advise anyone to just update to the new version at the moment. Especially not if they are administered by customers themselves. But I hope for the updated version, because in general everything is pretty cool.
