 * Great plugin, but I’m noticing a PHP error:
 * `"PHP message: PHP Warning: preg_replace(): The /e modifier is no longer supported,
   use preg_replace_callback instead in /var/www/...../wp-content/plugins/upstream/
   includes/class-up-comment.php on line 347" while reading response header from
   upstream`
