The Permalink for this post is: joymercier-wac3 the slug is the same.
It’s replacing a page: learn (this is my Posts Page with a slug of “learn”)
It currently has one Category chosen, Home page features, which is working correctly.
If I choose a category of Dog Agility (slug:dog-agility), and Interviews (slug:interviews). It will replace all of those pages with the post content.
So it’s not a permalink or slug conflict that I can detect.
Have you got any other ideas? I really appreciate your help!
