I'm registering the following post type:
register_post_type( 'post', array(
'hierarchical' => true,
'public' => true
) );
Now I have duplicate "Pages" menu items in WordPress Admin Menu. It should be not "Pages" but rather "Posts".
In older versions of WordPress ( < 4.4 ) everything was alright. Any suggestions to do the same? Most important is to make my posts hierarchical.
