The wrong site title is coming up for home page
Normally the &lt;title&gt; element is set in template_preprocess_html

  // Construct page title.
  if (drupal_get_title()) {
    $head_title = array(
      'title' =&gt; strip_tags(drupal_get_title()),
      'name' =&gt; check_plain(variable_get('site_name', 'Drupal')),
    );
  }
  else {
    $head_title = array('name' =&gt; check_plain(variable_get('site_name', 'Drupal')));
    if (variable_get('site_slogan', '')) {
      $head_title['slogan'] = filter_xss_admin(variable_get('site_slogan', ''));
    }
  }
  $variables['head_title_array'] = $head_title;
  $variables['head_title'] = implode(' | ', $head_title);


That is then output in your theme html.tpl.php 

You may have some code or configuration overriding the default title there in a module or theme.

I'd suggest searching through the codebase for the title text, or perhaps in a db dump file.

After that, you can either update it, or add some code for your own HTML &lt;title&gt; logic.
