I'm getting quite frustrated setting up the correct URL structure for a CPT with a custom taxonomy.

I have a CPT called 'courses' with a custom taxonomy called 'course type'. The url structure should be: site.com/courses/course-type/course-single-post. For example: site.com/courses/science/rocket-to-the-moon/

site.com/courses/ returns a 404

site/com/courses/science/ shows an archive page with all posts in side that custom taxonomy which is correct

site.com/courses/science/rocket-to-the-moon/ shows the single CPT which is correct too

Thing is , I don't know why the site.com/courses returns a 404 instead of showing an archive page listing all CPT's...?

This is the code that I've used:

I'm getting quite frustrated setting up the correct URL structure for a Cutom Post Type with a Custom taxonomy.

I have a Custom Post Type called courses with a Custom Taxonomy called course-type.

1. The URL structure should be: site.com/courses/course-type/course-single-post/.
2. For example: site.com/courses/science/rocket-to-the-moon/

• site.com/courses/ - returns a 404
• site.com/courses/science/ - Shows an archive page with all posts in side that custom taxonomy which is correct
• site.com/courses/science/rocket-to-the-moon/ - Shows the single Custom Post Type which is correct too
