I wish I a pearl of wisdom to add, but I too am experiencing empty titles & metas tabs since upgrading yoast (I use the twentyeleven theme). I deactivated all other plugins (none of which have been mentioned as causing conflicts, but I tried anyway) – to no avail. I have tested in multiple browsers and rolled back to 1.2.7, but I still cannot get meta and titles to work! Arrghh…any suggestions are greatly appreciated!
