Broken Link in WP Site?

Question

I've built a test site for a client using a theme purchased from Template Monster. I can't seem to find out why the link is broken on this page. and the Template Monster support has extremely poor.

http://trustlabor.com/riverstonesalonspa/portfolio/

I renamed the stock theme "Portfolio" page to "Staff Bios" If I change the page permalink to: http://trustlabor.com/riverstonesalonspa/staffbios/ to match the new name of the page it is a broken link. It's still looking for the stock theme subdomain "portfolio."

Furthermore the page navigation below the thumbnail photos is also broken. If you try to navigate to from Page 1 to Page 2 of the staff photos you get a 404 error message.
