Hello,
I figured it out (I think!!!) without changing code.
Removed the 301 redirects from my host cPanel.
Added 301 redirects in Wordpress SEO (I guess that means I won't be moving from this plugin for a while!).
Set my Home pages to noindex as I don't use them in my menus.
Not sure if this will beat me up in the search engines but will figure that out as I proceed.
Pete
