I think the trick lies in
/www/report/log/index.php
in particular this line (for me #168)
$userinfo = fullname($u, has_capability('moodle/site:viewfullnames', $context));
I don't want "fullname" I want simply $user
Will this show user ids? (or whatever is for user login name?)
Hoping to attract your attention
Being extra-sorry for sorta bumping this up...
Kind Regards
