WordPress 3.7 Update Issues

WordPress Version 3.7
Version 3.7

After attempting an automatic update to my self-hosted WordPress install from version 3.6.1 to version 3.7, within the admin panel, the site returned a completely blank page… I was unable to log back in to the admin panel at all, and the public site was down as well. The resulting URL displayed in the window contained:


…and in the the error log (viewable via FTP) was the entry:

Call to undefined function wp_get_current_user() in /wp-includes/user.php on line 215

In the WordPress.org › Support » Installation forum, user photoMaldives had the fix posted here… nice job.
