		<p>The Lilac updater requires that the current configuration file at <em><?php echo dirname(__FILE__) . "/includes/lilac-conf.php";?></em> is writeable. It is

           - Temporary set the file permission of file <em><?php echo dirname(__FILE__) . "/includes/lilac-conf.php";?></em> to 777. After installation set back to defaults.<br />
           - Temporary set the owner permission of file <em><?php echo dirname(__FILE__) . "/includes/lilac-conf.php";?></em> to the webserveruser. After installation set back to defaults.<br />
