I have a problem. when I have duplicate post titles:
Post 1 titles "Story" link: https://domain.com/story-1.htlm
Post 2 titles "Story" link: https://domain.com/story-1-2.htlm
and cpt name "chap", have a child relationship with the main post. I posted a chapter:
Chap by Post 1 titles "Story", link: https://domain.com/story-1/chap-1.html
Chap by Post 2 titles "Story", link: https://domain.com/story-1-2/story-1-chap-1.html ==> normally not duplicate post titles the link must be in the form: https://domain.com/story-1-2/chap-1.html ==> this chap error 404!!!
How do I fix this error?
I tried changing the title for the titles to be different, (code: Automatically add words if duplicate post titles)
and change the link as the titles for the link become different (code: Force post slug to be auto generated from title on save)
but it not work, still error T_T
