I assume the cronjob function is working as I get email (allowed so I can trap issues for now). The email states:
Status: 404 Not Found
X-Powered-By: PHP/7.3.19
Content-type: text/html; charset=UTF-8
No input file specified.
I wanted to have the sales->order list updated frequently so new orders and status updates would show automatically, but obvioulsy need support with this.
