Having just read the thread over here, I went and rechecked that my WordPress “secret” setting as listed in /wp-admin/options.php matched the setting in my bbPress admin-stettings-wp-integration screen and found that somehow they no longer matched. My best guess is that in the database “update” with the 2.5.1 upgrade of WP, it regenerated the database secret, thus killing the integration.
