Looks like you fixed it already. Sidebar and footer for your Group Forums Directory showing up in FF and even in IE6.
Thank you mercime for your quick response.
The sidebar and the footer disappear only when I am logged in as “admin” and not for regular members.
The problem it’s not visible when you are logged out or logged in as member, but is still present for logged in “admin” (administrator).
I found out why I couldn’t see the sidebar and the footer.
One of the plugins were conflicting with BuddyPress.
I deactivated All In One SEO and now everything works fine.
