Thanks!
I flushed the permalinks, flushed the cache etc.
Right now, both website.com/recipe/demo-recipe/ and website.com/demo-recipe/ are working URLs.
When I go to my blog archive page, unfortunately it’s still the website.com/recipe/demo-recipe/ URL that is listed.
Do I need to set up a regular expression to fix this? I had assumed that it would be an option in the plugin.
