I've modified my LocalConfig.php file to include the following at the end (MediaWiki 1.6.8):

$wgGroupPermissions['*' ]['createaccount'] = true; $wgGroupPermissions['*' ]['read'] = true; $wgGroupPermissions['*' ]['edit'] = true; $wgGroupPermissions['*' ]['createpage'] = true; $wgGroupPermissions['*' ]['createtalk'] = true; $wgGroupPermissions['*' ]['upload'] = true;

Also, the images directory and all directories/subdirs in it are fully writable.

Even with this, MediaWiki says that you must be logged in to upload images.

Is there a php cache that needs to be cleared for the new settings to be loaded? Or am I missing the effect of another setting.

Thanks, Ken
