Automatically check “Allow comments” for custom post type [duplicate]
This answer here fixed it for me: https://wordpress.stackexchange.com/a/243732/138177 add_filter( ‘comments_open’, ‘my_comments_open’, 10, 2 ); function my_comments_open( $open, $post_id ) { $post = get_post( $post_id ); if ( ‘myCustomPostType’ == $post->post_type ) $open = true; return $open; }
