Hello,

I think that I setted up everything correctly. I try to buy with a test accont a course, LINK: https://www.rules-chess-strategies.com/en/rules-chess-strategies-courses/4-easy-steps-to-master-the-grand-prix-attack

On payment settings I use direct

I checked the SP LMS // options // orders // I edited this mail. Then I log in into the website and go the above mentioned link. However on my mail I receive an error message like this:

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:

Am I doing something wrong?

Thanks in advance, Angelo

Note: Please also note that one student can buy a course again and again with payment system; if his order remails unpublish on dashboard and option tab.

Please advice.
