 Wordpress Version: Version 4.9.8
 Multiblog installation with several Blogs on one domain

 - main blog with URL https://daschmi.de/
 - another blog with URL https://daschmi.de/blog1

 Problem

 On the root Blog i can not create a page with the page name "blog1" on a
 subpage.

 Example URL: https://blogoverview/blog1

 The problem is the funtion avoid_blog_page_permalink_collision in /wp-
 admin/includes/ms.php:640

 workaround for me after the is_main_site() check:
 {{{
 if ($data['post_parent'] > 0) return $data;
 }}}
