I'm new to this plugin, but is the support forum around here always so busy? Wow.
Okay, I'm using WP 3.3.2 and SEO 1.2.1
I get this error at the top of the admin pages:
Notice: Undefined index: title-page in /home/xxxxxx/public_html/wp-content/plugins/wordpress-seo/inc/wpseo-non-ajax-functions.php on line 297
I haven't discovered where this might be a problem, but I'm guessing it's not good.
