I've just downloaded and installed MediaWiki 1.16. (MediaWiki 1.16.0 / PHP 5.2.11 ***cgi*** / MySQL 5.0.85 Default installation, no extensions.)
Everything seems to work okay BUT whatever changes I make to wgGroupPermissions ...have no effect whatsoever. (Changes to other variables in LocalSettings.php, e.g. $wgLogo, work fine.)
I've tried various examples from the help files, .e.g. $wgGroupPermissions['*']['edit'] = false; or $wgGroupPermissions['*']['read'] = false; ...but none have any effect whatsoever, i.e. I'm not able to make any changes to permissions -- it always stays in the default, "anybody-can-edit" mode.
More details: (1) I make the changes in LocalSettings.php and upload it; (2) I go to the wiki without logging on; (3) The wiki still lets allows anonymous editing of all pages.
Am I doing something wrong, or is this a bug? Please help!
