This appears to be an issue when using the permalink structure http://mydomain.com/sample-post/
I have a page with the URL http://localiswhereitsat.com/google-business-page/
This morning I published a post that I had (unintentionally) given the same slug to. When I went to View Post it took me to the page, not the post I had just published.
I renamed it http://localiswhereitsat.com/well-developed-google-business-page/ but WP shouldn't allow this. IMHO, it should treat it like a duplicate post URL and give it the slug http://localiswhereitsat.com/google-business-page-2/
Can anyone verify that this is really a bug and not unique to my installation?
