My site is currently running WordPress 3.5.1
I have created a page (not post) called "Child" with a parent page called "Parent". The child page does not appear to be inheriting the parent page within the permalink structure.
The parent permalink is http://site.com/parent/ and the child page is showing as http://site.com/child/
What I want to happen is for the child page permalink to be http://site.com/parent/child/
I haven't made any changes to the basic structure of the site. It is running the standard "Twenty Twelve" theme.
Any help will be greatly appreciated.
While creating a page you need to select parent page from page attributes column in the right hand side
Under Settings-> Permalink tab
create custom structure like - /%postname%/
FYI - Tested at my end and URL created like - http://localhost/wordpress/sample-page/page-2/
