I have been noticing an issue with this.
When I generated the PHP code from ACF > Tools > Export, I could not see any “archive” key/value field in the PHP code.
I created a hierarchical taxonomy called ‘course_categories’. It generates the category URLs like these:
https://example.com/course_categories/craft/ <- working
https://example.com/course_categories/craft/jewellery/ <- working
However, this link: https://example.com/course_categories/ always returns page not found.
How do I resolve this?
