I have this same problem!
I get a double url when I click the link for new posts.
The code in the header template does not show this.
when I look at the source for the home page, it shows
http://www.gotakeahike.com/forum/htt...hike.com/forum...
but the template only shows it once.
I cant figure out how to get it to not rewrite itself. I have even tried tremoving the first instance from the template thinking it would solve the problem but it didnt.
