WordPress version: 3.4.1
WordPress SEO version: Development version (Nov/8/2012)
I did this: Installed, gave titles to posts and pages.
I expected the plugin to do this: Show titles on posts and pages.
Instead it did this: Showed titles on pages, but URLs instead on posts.
Inserted <title><?php wp_title(''); ?></title> to the header.php - didn't work.
Deactivated all plugins, tried again - didn't work.
The post's code doesn't even show a <title>-tag.
What to do?
