Website is unable to be viewed, perplexing error message

` /** * 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(‘./wp-blog-header.php’);

Above is the message given when I go to the site, was trying to utilize a plugin when it happened. I figure it is missing a file or a file is corrupt but I do not know how to remedy issue. Any help from those more knowledgeable than me would be greatly appreciated.
