Thank you very much Marta. It works perfectly for me. I'll continue testing the module to find the problem...
Alberto, do this, please:
- Assign a student to your course;
- Login as this student account (can use "login as" function);
- Get the certificate;
- Verify the QR code;
- Logoff and login as moodle Admin (as administrator);
- Go to report page and you should see the issueds certificate list;
This module don't save Admin's certificate
Thank you Carlos! Indeed, everything worked fine when I enrolled as a student.
I thought I had tested this option as a student, but I was enrolled as a non-editing teacher (I should change my role in any of the tests)...
Sorry about the time I made you lose.
No problem
