Hello,
I have the same issue.
I have 3 parent pages : parent1, parent2 and parent3
I have child page for all of them : child1-of-parent1, child2-of-parent1, child1-of-parent2, …
My URLS are :
– /parent1 , /parent2 and /parent3
– for child pages : /child1-of-parent1, …
A lot of pages are redirected to bad pages :
– some pages (not all of them) generates duplicate content with this kind of URL : /child1-of-parent1/child1-of-parent1
– these kind of pages are redirected to /blog instead of 404 -> /parent1/child1-of-parent1/any-slug-which-not-exist …
