In most WordPress websites the author pages functionality isn’t needed. For search engines it can create unwanted duplicate links to your content.
There are a few solutions to the problem. A couple are: get a plugin or create an author template for your theme / child theme. I will be showing you how to create an author template.
The Quick Tip
In your theme directory place the following into author.php
<?php // Disable author pages // PHP permanent URL redirection header("Location: /", true, 301); ?>
This does a permanent redirect to your home page.
Its a quick and easy way to get the job done.
