I've noticed that Google is indexing a page with the url
That page just displays the same as site.com/ so it's duplicate content.
Is this normal, or something that might be created by a plugin?
I tried putting in a redirect from site.com/?view=archives to site.com/ with the Objection Redirection plugin but it doesn't work.
For archives I'm using SRG Clean Archives http://www.idunzo.com/projects/clean-archives/ version 4.3, but it is used on a page and has a static url /archives/.
