 * Just updated from 202 to 204.
    On running upgrade, I get this error:
 * Fatal error: Call to undefined function: wp_get_referer() in /home/knotty/public_html/
   mydomain/wp-admin/upgrade.php on line 70
 * If I just try to log in without running upgrade I get:
 * Fatal error: Call to undefined function: wp_get_cookie_login() in /home/knotty/
   public_html/mydomain/wp-login.php on line 180
 * What do I do now?
 * Thanks..knotty

 * FIXED. Sorry my mistake!
 * In the instructions under do not delete, I did not delete the wp-includes.
 * Got confused here since it was listed under do not delete.
