Thread:Manual talk:Installation guide/MW1.15 to 1.18 Problems with Autoload?

Got Problems while /config/ via web-mask:

Fatal error: Class 'SiteConfiguration' not found in /HAwww/apache/htdocs/wiki/includes/DefaultSettings.php on line 32

vi wiki/includes/DefaultSettings.php [...] $wgConf = new SiteConfiguration; [...]
 * 1) Create a site configuration object. Not used for much in a default install.
 * 2) Note: this (and other things) will break if the autoloader is not enabled.
 * 3) Please include includes/AutoLoader.php before including this file.

vi wiki/config/index.php [...] require_once( "$IP/includes/Defines.php" ); require_once( "$IP/includes/DefaultSettings.php" ); require_once( "$IP/includes/AutoLoader.php" ); [...]

yes, AutoLoader.php is in wrong order :-\
