Issue
-----

In rare cases, Drupal can show "A client error happened" inside content. The usual reason for this is because a browser, often Google Chrome, sends a `Forwarded` header. Symfony, an underlying library for Drupal, will display this message if it is confused by that header.

Resolution
----------

To avoid this, make sure you have an up-to-date Drupal install, adding this code to your `settings.php` file (or [post-settings-php hook](/node/57275) for Site Factory customers):

    unset($_SERVER["HTTP_FORWARDED"]);
