Please help.

Can't seem to find a work around.

I was indexed on google Prior to installing Simple SEO.

After installing Simple SEO google then indexed my new urls.

However the old urls are still there pointing back to the same content.

I cant get google to remove the urls because one they need to return a 404 not found.

Has anyone experienced simplilar duplicate content issues due to simple seo??

Any solutions?

Phil
