Fixing Duplicate Pages Titles/Content

[VeronicaCFowler]

I have a DNN site, which I created friendly URL's for; however, the creation of the friendly URL's then created duplicate page content and titles.  I was able to fix all but two URL's with rel="canonical" links.  BUT The two that are giving me the most issues are pointing to my homepage.  When I added the rel = "canonical" link the page then becomes not indexable.  And for whatever reason, I can't add a 301 redirect to the homepage because it then gives me "can't display webpage" error message.  I am new to SEO and to DNN, so any help would be greatly appreciated.

In Google's webmaster blog this year, they announced that the algorithm prefers that you use rel=next and rel=prev instead of rel=canonical.

I'm having trouble understanding the way your question was worded but I hope this can help.
