With Advanced Page Manager 1.2 installed, I do not have an "Add new" option under Pages and selecting "+ Page" from the WP menu just brings me to the main screen of the Advanced Page Manager.
The only option appears to be an "Add New" button beside the "Template" column. While this may actually work, I'm reticent to use it because it appears to be for adding a new template. Either way, when you do click on it there is a notification saying that you are "adding a page related to this page", which I do not want to do. I want to make a new main page (not a child or sub page).
All the best,
