I've got version 2.8 of Wordpress and 3.2 of atahualpa. I installed version 1.5.6 of All in One SEO but the meta tags and meta description does not display when using the atahualpa theme.
I went to the All in One SEO FAQ page and it says to insert <?php wp_head(); ?> in the header.php for the theme but that line is already there.
I did a fresh install on a test site for giggles. Installed Wordpress, then installed and configured All In One SEO. Everything worked fine. Metatags and description showed up fine.
Then I installed atahualpa with the SEO option turned off and my metatags and description disappear.
Switch back to the default theme and the metatags and description show up again.
I'm at a loss and am losing hits. Has anybody else experienced this problem or solved it?
