Index

I am very new to WP and to Enfold.
In FTP I can see an index.php
However if I open fb-design.co.uk/index.php webpage
I get error not found.

The code on the server in the index page is
<?php/**
* Front to the WordPress application. This file doesn’t do anything, but loads
* wp-blog-header.php which does and tells WordPress to load the theme.
*
* @package WordPress
*/

/**
* Tells WordPress to load the WordPress theme and output it.
*
* @var bool
*/
define( ‘WP_USE_THEMES’, true );

/** Loads the WordPress Environment and Template */
require __DIR__ . ‘/wp-blog-header.php’;

I have another page called Home which opens normally and would be OK as the index/homepage

Have you any idea where I may be going wrong please?
Thank you
John Hardy
