Version 1.19.2
Every now and then, on a random page, we'll discover that an anonymous user will see
the rollback link on the history page, and actually be allowed to rollback changes to a
page. How is this possible? Is this a known problem? Am I doing something wrong? I have
the following set in LocalSettings.php
$wgGroupPermissions['*']['rollback'] = false;
$wgGroupPermissions['user']['rollback'] = false;
$wgGroupPermissions['rollback']['rollback'] = true;
$wgGroupPermissions['sysop']['rollback'] = true;
And anonymous can still see the rollback link.
