BuddyPress.org

‘wp_bp_activity_sitewide’ doesn’t exist anymore, not even in the deprecated code. It was dropped pre 1.0 in lieu of having one universal activity stream. A clean 1.1.3 installation shouldn’t have any code looking for those tables.

http://socialpress.co.za/activity/feed works for me.

I’ve created a test account on your website and confirmed that I was able to delete my own activity just fine.

Is it possible this is a conflict with the privacy component?
