My site has a static landing page with buttons to go to Cait's content or Shannons's content. Each author's page will feature their own posts, as well as a section with their social media streams. It is vital that these two author's content is kept separate.
Currently, I'm using conditional tags in the header to take care of this but I've ended up with nothing but blank author pages. Any ideas how I can rectify?

header.php-

```
<!DOCTYPE html>
<html>
<head>
    <meta http-equiv="Content-Type" content="<?php bloginfo('html_type'); ?>; charset=<?php bloginfo('charset'); ?>" />
    <meta name="generator" content="Wordpress <?php bloginfo('version'); ?>" />
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
    <title><?php bloginfo('name'); ?> <?php wp_title(); ?></title>
    <link rel="pingback" href="<?php bloginfo('pingback url'); ?>" />
    <link rel="alternate" type="application/rss+xml" title="RSS 2.0" href="<?php bloginfo('rss2_url'); ?>" />
    <link rel="stylesheet" href="<?php bloginfo('stylesheet_url'); ?>" />

    <?php wp_head(); ?>
