Hi,
I installed the customcert plugin on Moodle version 3.5.3, and added a certificate as an activity to one course.
Everyone is able to issue & download the certificate from My Certificates link, but as a site administrator I am only able to download my own certificate. I do not see the list of issued certificates. I used different group modes (No groups, Separate groups, Visible groups) without any difference. It shows "Nothing to display" as in the attached image.
Meanwhile, I checked the view.php code, and in the below code, changed the !$canmanage to $canmanage, and now I can see the issue date of my own certificate as in the attached image.
if ($issues && !$canmanage) {
// Get the most recent issue (there should only be one).
$issue = reset($issues);
$issuestring = get_string('receiveddate', 'customcert') . ': ' . userdate($issue->timecreated);
$issuehtml = $OUTPUT->box($issuestring);
}
