I’d suggest “Advanced Content Pagination” WordPress plugin. I use it on my site. It gives each page pagination buttons of that post a different title, description and image.

Try this:

<?php wp_reset_query(); ?>
<?php query_posts(array("post_status" => "publish", "orderby" => "post_date", "order" => "DESC", "posts_per_page" => 1)); ?>
<?php while (have_posts()) : the_post(); ?>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
<?php the_excerpt(); ?>
<?php endwhile; ?>

This will show the latest one post you have.

Great!

Have you reset your cache?

Also, is your wordpress really located in /www/ folder, which is in the same /home/therapy/www/ directory? I mean /www/www/ looks not good for me.

Open your wp-load.php (located in root directory) and check, is there such a row?

require_once( ABSPATH . WPINC . '/functions.php' );

This code will output User post thumbnails but only for user who has only one post. What exactly you need, let me know and I can say what to add in if{ } else { } statement?

/********************************************************************/
/* Function for displaying related post thumbnails */
/*********************************************************************/
function get_related_author_posts() {
    global $authordata, $post, $wpdb;

    $authors_posts = get_posts( array( 'author' => $authordata->ID, 'post__not_in' => array( $post->ID ), 'posts_per_page' => 7 ) );
	$author_post_number = $wpdb->get_var("SELECT COUNT(*) FROM ".$wpdb->posts." WHERE post_author = ". intval($authordata->ID) );

	if( $author_post_number == 1){
		$output = '<div class="tiles-block"><h4 class="other-props" >Other properties by this developer</h4>';
		foreach ( $authors_posts as $authors_post ) {
		  $output .= '<a href="' . get_permalink( $authors_post->ID ) . '">' . get_the_post_thumbnail($authors_post->ID) . '</a>';
		}
		$output .= '</div>';
		return $output;
	}
}
