The post type url doesn’t work

Hello guys!
I have just installed the plugin. It works for the posts but it doesn’t work for the main post type.

Example
the main is
http://www.boundlessroads.com/vegan-recipes/ (which doesn’t work)

One of the sub-posts is, for example, this one
https://www.boundlessroads.com/vegan-recipes/the-most-delicious-veggie-burger-recipe/

and they work fine.

I have tried to shut down all the plugins in case of any conflicts, but still dosen’t work.

thanks for your help
cheers
Isabella
