I made three (suggested) updates to my modules, updating automatically through the system, and this "brought down" the back end of my system. Anyone logged into the system sees an error on navigating anywhere on the web site (front or back end), while non-users can access the front end of the web site. www.westsidetrainingcenter.com. My attempts to upload the most recent backups is not working, so I have been forced to use the file system that prevents me from accessing the back end of the system for the time being, so other people can still access the front end (static web site). It's running the current version of Drupal 8.
The error, whenever anyone logged into the system attempts to access either the front or back end, is: The website encountered an unexpected error. Please try again later.
