Here is the error I receive:
Failed to configure Business Manager. See the log below for details and fix the problems if possible. Business Manager will restart the configuration procedure next time you log in to it.
Info: Installation has been completed with errors.
CauseThe error indicates that the %plesk_dir%\admin\plib\api-rpc\Agent.php file is missing, probably because it was removed in response to a known vulnerability.
ResolutionThe solution is to replace the file using the steps described in the following article:
