I've searched the forums and cannot find if there ever was a resolution to the problems of getting ATA sidebars to show up on BuddyPress pages. All of the old threads just kind of peter out without any solution.
I've been using a different theme for some months as I couldn't solve it but the theme I am using is really resource hungry generating hundreds of queries per page and consequently very slow page loads.
I know the bit about adding the get header code and I have no problem with the header showing up. The problem is getting the sidebars to display on a page like domain.com/members/USERNAME or domain.com/members/USERNAME/activity/
From checking on a couple of sites that used to have the problem I see one's moved to a customized version of the BP Default theme and another seems to have figured out the fix for ATA.
Perhaps someone knows what the key difference is between a theme like Suffusion that handles the sidebars without incident and ATA? If that is known we could adapt to imitate the Suffusion functionality?
