I am getting the same problem as related here: http://moodle.org/mod/forum/discuss.php?d=176491 . I can see that this has been raised as a tracker issue and resolved, so new installs of Moodle won't have this problem, but I can't see how to patch my existing installation to fix the bug. I installed Moodle 2.1 on 06/07 and from what I can see here ( http://tracker.moodle.org/browse/MDL-27040?page=com.atlassian.jira.plugin.system.issuetabpanels%3Aall-tabpanel#issue-tabs ) , the file that is to be amended is lib/accesslib.php and the code to be changed/added is :
if (!empty($viewallgroupsusers)) {
$wherecond[] = "($grouptest OR u.id IN (" . implode(',', array_keys($viewallgroupsusers)) . '))';
} else {
$wherecond[] = "($grouptest)";
}
around line 5010. However, when I add this (or replace the whole accesslib file, which I've also tried), I get a different error:
---------
Database transaction error
