BuddyPress.org

The “registration” page always has a sidebar and I would like to use a full-width page template. I have already set the “registration” page to full-width template on the page edit and it makes no difference. How do I remove the sidebar?

registration page:
http://lawestside.org/register/

I am using fruitful theme, but it doesn’t seem to make a difference, the sidebar is there no matter what theme I am using.

Thank you.
