How to allow different authors to use same post slug?
I ended up adding this code that makes the default post type hierarchical and populating the wp_posts.post_parent field with the author ID. The combination of these two has achieved the desired implementation of having the same slug across multiple authors. // Set post type “post” to be hierarchical $wp_post_types[‘post’]->hierarchical = 1; Source: https://stackoverflow.com/questions/10750931/wordpress-how-to-add-hierarchy-to-posts
