Hi @jayon,

This error indicates that some files are missing.

I recommend downloading a fresh copy of the WHMCS files from https://download.whmcs.com , uploading the zip file to your server, and extracting it, making sure that all the files are overwritten successfully.

Here is a guide to resolving this error: https://help.whmcs.com/m/updating/l/1240688-troubleshooting-a-php-fatal-error-class-not-found-error
