# Cannot post comments after WordPress 3.9 upgrade

 * I upgraded to WordPress 3.9 yesterday but now I cannot post comments on the site.
   I get the following error:
 * >  <b>Notice</b>: Undefined variable: _SERVER in <b>(URL)/wp-comments-post.php
   > </b> on line <b>8</b>
 * I have tried reinstalling 3.9 without success. I have also reverted to the default
   twentyfourteen theme and disabled all plugins which also has no effect.
 * Can anyone suggest what might have gone wrong? The portion of code in wp-comments-
   post.php it is referring to reads as follows:
 * > if ( ‘POST’ != $_SERVER[‘REQUEST_METHOD’] ) {
   >  header(‘Allow: POST’); header(‘
   > HTTP/1.1 405 Method Not Allowed’); header(‘Content-Type: text/plain’); exit;}
