How to display your site title in the browser tab
This is what worked for me. Your mileage may vary.
1. Edit the following file:
<your_blog>/wp-content/themes/<your_theme>/header.php
2. Find the line:
<meta http-equiv=”Content-Type” content=”<?php bloginfo(‘html_type’); ?>; charset=<?php bloginfo(‘charset’); ?>” />
3. Add the following line after the line shown above.
<title><?php wp_title(‘«’, true, ‘right’); ?> <?php bloginfo(‘name’); ?></title>
4. Save the file and upload it to the same place on your website.
5. Reload your blog site and hope something else isn’t overwriting your site name.
