author.php duplicate info

[fmf]

I am using the author.php page from the agent theme to create individual author pages within the news theme. I had no trouble implementing this and the page worked exactly as expected until last monday when suddenly the author information began to duplicate. I had not changed the code. I have tried:

- changing showposts to 0 / 1 / 2 (i get 6x / 2x / 3x info respectively)
- posting the agent author.php file as-is (still get 2x info)

Any help would be appreciated!! BTW i am running WPMU

Example URL: http://msmagazine.com/blog/blog/author/admin/

thanks in advance,
Courtney

p.s. i posted this over at the agent board a week ago but didnt get a response - thought it might be better over here
