What the . . ! Duplicate Pages and Titles WAY up?

[damon1212]

My duplicate pages went up 50 plus in the past week, and my duplicate page titles went over more then 100.

We recently redesigned the website, but it has been up for several weeks now.  The only change I made specifically last week or late the week before was to get my 301 redirects done to get the www. version and the non www version pointing to the same place (as well as a couple other sites that point to it).

I'm sure this is not enough info to figure out what went wrong . . . I'd love some help in figuring this out though.

Are you using an ecommerce software? What software are you running?

Joomla.

It could be something from Joomla, like it's creating printable versions of the pages. Are you still having this issue? Do the reports of duplicate pages give you any clues form the URL?
