You just need to set the PHP Error log path.
The PHP Error Log Location Set To: folder path does not match the Error Log Path Seen by Server: folder path. Click Here to go to the PHP Error Log page… and instead of clicking on the Read Me button just set your Error log path.
The Error Log Path Seen by Server: should be something like /home/content/xxxx/public_html/wp-content/bps-backup/logs/bps_php_error.log
and you would just copy that path to the PHP Error Log Location Set To: text box and click the Set Error Log Location button.
