 * I’ve started getting errors when using this plugin.
    When I change a user’s role(
   from subscriber to editor, for example), I get a white screen with the following
   errors:
 *     ```
       Notice: Undefined index: user_login in /srv/users/sp/apps/sp/public/t/wp-content/plugins/force-first-last/force-first-last.php on line 42
   
       Warning: Cannot modify header information - headers already sent by (output started at /srv/users/sp/apps/sp/public/t/wp-content/plugins/force-first-last/force-first-last.php:42) in /srv/users/sp/apps/sp/public/t/wp-includes/pluggable.php on line 1251

       ```
   
 * What’s wrong, and how can I fix it?
