After using Softaculous from Cpanel to do an auto upgrade, i started getting Error "Oops Something went wrong and we couldn't process your request" error. I worked with my hosting company to solve the first Oops 403 which is a permission error. Now the front end is working well but i can't login to the back end admin panel. Below is the error code that i got after entering user name and password and i turned the error log on from the SQL to show the detailed error page. Please can someone tell me what is going on and Why thanks in advance. Error: Class 'WHMCS\Installer\Update\Updater' not found in /home/*****/public_html/vendor/whmcs/whmcs-foundation/lib/Admin/Controller/HomepageController.php:0
