 * On WordPress 4.3.1, when logging in from wp-login.php, I can access the login
   page but see errors. However, after logging in with my credentials, both wp-admin.
   php and wp-login.php will load to a white page with just errors:
    **wp-login.
   php shows:** Warning: Cannot modify header information – headers already sent
   by (output started at /nfs/c04/h06/mnt/180548/domains/example.com/html/wp-includes/
   user.php:9) in /nfs/c04/h06/mnt/180548/domains/example.com/html/wp-login.php

 * **wp-admin only shows:**

   wp-includes/pluggable.php on line 1207
 * I assume I should be looking at user.php line 9… which is just a commented out
   statement:
 *     ```
       <?php
       /**
        * WordPress User API
        *
        * @package WordPress
        */
       /**
        * Authenticate user with remember capability.
        *               (<--- This is line nine)
        * The credentials is an array that has 'user_login', 'user_password', and
        * 'remember' indices. If the credentials is not given, then the log in form
        * will be assumed and used if set.
        *
        * The various authentication cookies will be set by this function and will be
        * set for a longer period depending on if the 'remember' credential is set to
        * true.
        *
        * @since 2.5.0
        *
        * @param array $credentials Optional. User info in order to sign on.
        * @param bool $secure_cookie Optional. Whether to use secure cookie.
        * @return object Either WP_Error on failure, or WP_User on success.

 * Going to try and upload the files from my dev site (aside from wp-config.php)
   as they’re supposedly identical but work just fine.
