Q&A plugin user profile page

I have an issue in the user profile page.

See this user page:

http://financetrain.com/questions/user/admin/

You will notice that the page shows http://financetrain.com/members/admin/ as the website name for the user.

I'm not sure from where this is coming because it returns 404 page. I used to use buddypress before. Is it because of that? If so, how can I fix it?

Thanks,
Manish
