BuddyPress.org

I know you’ve solved the problem but I recently used this as a solution, this code removes the Blogs button from both your “My Account” menu in the admin bar, and the Blogs button in your profile navigation.

Put this code in your bp-custom.php file:

function remove_blog_buttons(){

remove_action( 'bp_setup_nav', 'bp_blogs_setup_nav' );

remove_action( 'admin_menu', 'bp_blogs_setup_nav' );

}

add_action('plugins_loaded','remove_blog_buttons');

I hope this helps
