Message while loading

I am receiving this message when trying to pull up my page:
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’);

Any thoughts as to why, it has been working for over a year, now this is coming up.

Then when trying to access the WP control panel I get this:

[Moderated – yes per the below, immediately change your passwords, etc.]

Thanks!
