Site Error Theme?

I have this Error on the Site:
?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';

Could you help or have a idea?
