BuddyPress.org

Hi,

I created some groups and now I would like to change the information for some of the groups/committees: http://cornhill.org/cornhillbeta/groups/. I’m using the latest version of WP and BP with the bp-community theme from wpmudev.

I’m signed in as admin and when I click ‘admin’ on the page I want to change (or from the group management in the dashboard) I get the following error:
Warning: Cannot modify header information – headers already sent by (output started at /home/content/c/o/r/cornhill/html/cornhillbeta/wp-content/themes/bp-community-child/functions.php:3) in /home/content/c/o/r/cornhill/html/cornhillbeta/wp-includes/pluggable.php on line 890

The problem started when I added the code from this page: http://wpmu.org/how-to-add-a-custom-default-avatar-for-buddypress-members-and-groups/. Is there another way to change the mystery man that won’t affect accessing the admin area?

Also, is there a way to change the group avatars after they have been created?

Thank you.
