Error message re: php file when typing in url

Hello, I get this message when typing in the url:

nt 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(‘./wp-blog-header.php’); ?>

Can anyone help please?

Thanks.
