 * I recently updated WP Offload S3 Lite from version 1.3 to version 1.42 (I also
   disabled and removed the Amazon Web Services plugin) on my multisite sub directory
   network and now I can’t delete items in any media library on my network. Here’s
   the error produced from my Nginx log file.

 * Your PHP config is missing the XML libs that WP Offload S3 Lite needs, and WordPress
   pretty much requires these days as many plugins need it.
