 * I’m getting a fatal error when I have Jetpack activated for some reason. The 
   problem started suddenly around January 19th. Jetpack for have an error and trigger
   WordPress to only be accessed in recovery mode.
 * Jetpack has to be deactivated in order for the website to work.
 * This is one of the notices in the debug logs:
 * PHP Fatal error: Uncaught Error: Class ‘Automattic\Jetpack\Connection\Rest_Authentication’
   not found in /home/bushorder/public_html/wp-content/plugins/jetpack/class.jetpack.

 * Hello, there.
 * I’m not seeing that Jetpack is connected at all to that domain at the moment,
   so I’m unable to test from this side to look for clues.
 * That being said, it sounds like something was conflicting with your Jetpack plugin
   itself.
 * Would you be able to delete the /Jetpack/ folder from inside your /wp-content/
   plugins/ directory? You can do so by accessing your server through FTP access.
   Your webhost can assist you if you need additional help on how to do so.
 * Afterwards, it would be a good idea to make sure that all of your plugins, theme,
   PHP version, and core of WordPress on that site are all updated before trying
   to install Jetpack again (your host can help with all of that if need be).
 * To play it extra safe, you can disable all of your other plugins except for Jetpack
   before you activate Jetpack again, then you can turn on your plugins one by one
   to make sure the PHP error does not happen again.
 * It should not give you this same error after this troubleshooting, but if it 
   does, please let us know and we can help from there. Thanks!
