 * I had backed up the site prior to updating. I updated a bunch of plugins, so 
   I restored plugins and DB. Everything returned to how it should be. I then only
   updated UAM and the same problems returned.
 * It also caused WP to not be able to upload media into the library. It always 
   gives an error and says to try again later.
 * I restored plugins and db again, updated all but UAM. Now everything is fine,
   so I won’t be updating to the latest version at this time.
