Hi Robert, the error occurred in the admin section. On your demo site it should be at: https://demo.mahara.org/admin/groups/groups.php (button copy). However, I do not have access to the admin section. Can you please verify this?
The name of the course was, for example "2021/2022 KPG/9ITV Informační a komunikační technologie ve vzdělávání". Copying from https://demo.mahara.org/group/nova-skupina-cestiny-dtn on the demo site actualy worked.

The bug is in version 21.10.04 and maybe elsewhere. It is caused by an error in the lib/group.php script on line 377. Here, strtolower is mistakenly used instead of mb_strtolower. The code on the line should be: if (get_records_sql_array('SELECT id FROM {group} WHERE LOWER(TRIM(name)) = ?', array(mb_strtolower(trim($data['name']))))) { Same problem is in group/edit.php: on line 481. Correct code is here: if ($ids = get_records_sql_array('SELECT id FROM {group} WHERE LOWER(TRIM(name)) = ?', array(mb_strtolower(trim($values['name']))))) { line 497 if ($ids = get_records_sql_array('SELECT id FROM {group} WHERE LOWER(TRIM(shortname)) = ?', array(mb_strtolower(trim($values['shortname']))))) { Regards.
