Yoast installed fine, I filled out the settings. But even after a restart, there's no sitemap where it says (molvray.com/acid-test/sitemap_index.xml), it doesn't generate SEO titles, under "snippet" it shows the permalink but no snippet. (I did edit my header.php file to have the
<title><?php wp_title(''); ?></title> line, and also checked "Force Rewrite Titles" in desperation.) My excerpt length is set to 100 characters in WP, but nothing shows up. And so on. When I enter a "Focus keyword" in the SEO section under a post I'm editing, it gives me page analysis, and seems to be seeing the post properly, but other than that: no signs of life.
What am I doing wrong?
