Why is my site title appearing twice in my browser tab?
If your site title is appearing twice in your browser tab, it's likely caused by an SEO plugin you have enabled. No worries, though! We have a quick fix.
Navigate to WP Dashboard > Appearance > Editor > and, on the right, open up the "header.php" theme file. Toward the top of this document, you should see the following line of code:
<title><?php wp_title('-', true, 'right'); bloginfo('name'); ?></title>
You can replace that line of code with the following instead:
<title><?php wp_title('-', true, 'right'); ?></title><span class="redactor-invisible-space"></span>
Be sure to save the changes made to the theme file when you're finished.
