Double titles

Hey I get double tites on my WordPress webpage!

I think it has to do with Yoast WordPress SEO reading from another thread.
If it matters, I am MafiaShare Rethink theme.

At first I went to header and changed <title elegant_titles… to <title wp_title.., after I did that I got a completely new header code, looking like this:

<title>
            <?php
            /*
             * Print the <title> tag based on what is being viewed.
             */
            global $page, $paged;
            wp_title('', true, 'right');
// Add the blog name.
            bloginfo('name');
// Add the blog description for the home/front page.
            $site_description = get_bloginfo('description', 'display');
            if ($site_description && ( is_home() || is_front_page() ))
                echo " | $site_description";
// Add a page number if necessary:
            if ($paged >= 2 || $page >= 2)
                echo ' | ' . sprintf(__('Page %s', 'rethink'), max($paged, $page));
            ?>
        </title>

On the Yoast plugin I tried Force Rewrite as well as changing title template. Nothing yet worked.

First post, thanks!
