BuddyPress.org

Thanks, but not sure if I understand. If I deactivate all plugins including BuddyPress, I not only can’t access the blogs but I can’t access my main page either. I get the following: Fatal error: Call to undefined function bp_page_title() in /home/cetateni/public_html/wp-content/themes/simple-wp-community-theme/header.php on line 9

Thanks for your help but please clarify.
