The problem is occurring on thegrandtour2012.com. [link]
I'm using WordPress SEO version 1.1.6 and Standard Preview 3. I cannot get the titles to rewrite. With your plugin activated the title is always the URL of the page. When I deactivate it the title reverts to the typical WP title structure.
I use your plugin on several websites and this is the only one experiencing this problem. It's the first time I've used this theme but I know you've personally worked on it already. I've shut down all other plugins and am no longer running a child theme.
I appreciate any help you can offer me.
