Drupal is one of those frameworks that shows up "ready for production."  In PHP, this means that error messages are suppressed, so on any error all you get is the white screen of death.  You may want to consider reconfiguring the installation so that error messages are displayed in the browser output stream. Or you may want to continue to suppress the messages, but add the error logging ability.

The PHP initialization settings for display_errors, log_errors, error_reporting, and error_log are in play and interact with each other.  If you look up those terms on http://php.net you will find everything you need to know.  In my dev environment, I use this:
error_reporting(E_ALL); 
ini_set('display_errors', TRUE);
ini_set('log_errors', TRUE);

I checked the Apache error log and followed through on a PHP error there. Thanks.
