Try this CSS, it will decrease the top and bottom spacing that you currently have setup:

.site-footer {
padding: 1em 2em;
}

Right now you have the padding there set to 2em. Which is creating the extra whitespace.

.site-footer {
padding: 2em;
}

Hope that this helps.

Seems to just have been a glitch, PDF’s are now viewable.

Changed the theme and reset the permalink structure this seems to be fixed now.

Was able to figure out both problems. For my main problem where the posts that were not showing up under both of the authors. By including the get_post_taxonomies function in the posts arguments array this seems to have fixed that main problem problem.:

<?php $author_args = array(
	'offset'                    =>  0,
	'orderby'                 =>  'post_date',
	'order'                     =>  'DESC',
	<strong>'include'                  =>  get_post_taxonomies( 'author' ),</strong>
	'author'                   =>  $contributor_id,
	'post_type'              =>  'post',
	'post_status'           =>  'publish',
	'posts_per_page'    =>  -1,
	'suppress_filters'     =>  true,
);

// Gets the posts for each contributor.
$posts = get_posts( $author_args );

if ( $posts ):
	foreach ( $posts as $post ) : setup_postdata( $post );

		// post information here

	endforeach;
endif; ?>

For the second problem with the duplication of the co-authors was solved by doing this,
although this could be improved upon:

<?php if ( $posts ):
	foreach ( $posts as $post ) : setup_postdata( $post );
		// Setting up the coauthors variable
		$coauthors = get_coauthors();

		// Counter for the coauthors foreach loop below
		$coauth = 0;

		// Counting the number of objects in the array.
		$len = count( $coauthors );

		echo '<div class="post">';
			// Meta data here...

			foreach( $coauthors as $coauthor ):
				// Updating the counter.
				$coauth++;

				// Getting the data for the current author
				$userdata = get_userdata( $coauthor->ID );

				// If one object in the array
				if ( $coauth == 0 ):
					// Just the authors name
					echo $userdata->display_name;
				// If more than one object in the array
				elseif ( $coauth >= 1 ):
					// Adding a "comma" after the name
					echo $userdata->display_name . ', ';
				// If last object in the array
				elseif ( $coauth == $len - 1 ):
					// Adding an "and" before the last object
					echo ' and ' . $userdata->display_name;
				endif;
			endforeach;

			// More meta data here...
		echo '</div>';
	endforeach;
endif; ?>

Hope that this helps someone else out in the future if they have a similar problem!!

I now believe that the problem for my multisite rss feeds not working correctly is that there is something wrong in the permalink structure if the URL’s are set to the /postname option as they seem to work and correctly function under the default structure option if I don’t have my custom theme turned on. Looking into what is interfering with the permalinks.
