 * I’m trying to enable the “S3 Offload Lite” plugin, and after I try to select 
   an existing bucket, I get an “Internal Server Error” from WP. Enabling debug 
   and watching the debug shows me this:
 * [10-Jun-2016 15:01:43 UTC] PHP Fatal error: Call to undefined function Guzzle\
   Stream\hash_init() in [REDACTED]/wp-content/plugins/amazon-web-services/vendor/
   aws/Guzzle/Stream/Stream.php on line 102
 * Am I missing a PHP module or something?
