Using latest version of Yoast WP SEO, I find that page titles have disappeared. I tested this on the minimal and generic child theme. I tried it with nothing in the functions file. Same result. All other times I looked at displayed Yoast’s titles correctly.
scott, i believe this has to do w/ the fact that thematic wasn’t meeting the guidelines for WP3.4… which is to put wp_title() in between the title tags and then filter in any changes. i know karin has patched this and gene has passed thematic 1.0.2 to ian for submission to the queue… so it should be available this week (next at the latest i would think).
