Your site seems to be running fine ? Have you updated your browsers. Also clear the browser cache and cookies.
look into header.php and see what code is used for
<title> ???? <?title>
this possibly should only be:
<title><?php wp_title(); ?><?title>
as you are doing the seo with a plugin <!-- This site is optimized with the Yoast WordPress SEO plugin v1.3.4.4 - http://yoast.com/wordpress/seo/ -->
Yes, an astute observation, when I activated the Yoast SEO plugin this problem started, it seems.
Now, here’s the code from header.php, and as I’m not a code person, it seems considerably more complicated that yours above:
<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 || $page >= 2)
echo ' | ' . sprintf('Page %s', max($paged, $page));
?>
</title>
Do I replace with your simpler version?
