Tested WP Version: 3.1
Tested BP Version: 1.2.8
Even though bbPress is turned off it appears in the drop down for search. But that is something else than I wanted to report.
When using the search bar to find members or groups (don't see blog search option) I get the following error:
Catchable fatal error: Object of class WP_Error could not be converted to string in /public_html/wp-content/plugins/wpmu-dev-seo/wds-files/wds-onpage/wds-onpage.php on line 153
