Welcome to the Q&A Forum

Hello there.. Regarding the problem you do experience with Google choosed not to crawl the pages, that was marked as duplicate content. I don't understand how the pages can look the same but have different content? That does not make sense, either the pages are the same or they are not. So if they have different content, they can't be the same and if google marked them as duplicate content because of canonicals. You can always ask them to recrawl the pages by creating a sitemap, make sure the new URLs are in it and then resend the sitemap in webmaster tools. Also, I would suggest you edit all the pages and change something on each of them from your WordPress administration. That will tell Google that something on the pages has changed. I hope this was a help ... [Signature removed by moderator and response edited to comply with Community Etiquette Guidelines.]
