We are building a new site currently at http://67.222.109.48/~cheapnan/ I started doing some SEO after the developer I hired failed to do it even though it was in the agreement. I did our old site so I should be able to do this but I am new to wordpress. Now when i go to the products tab at the top of the page the first 2 have broken links, I checked the rest and there are 3 total that I need to fix.  I am unsure how to access the navigation so I can fix the links.  Please tell me where to look.

when moz crawls my site they say I have 2x the pages that I really have & they say I am being penalized for duplicate content.  I know years ago I had my old domain resolve over to my new domain. Its the only thing that makes sense as to the duplicate content but would search engines really penalize me for that? It is technically only on 1 site.  My business took a significant sales hit starting early July 2013, I know google did and algorithm update that did have SEO aspects.  I need to resolve the problem so I can stay in business
