Thank you, now I only have these errors:

Notice: Undefined variable: deletedHashLevel in /w3/httpd/docs/mediawiki/LocalSettings.php on line 170

Warning: Cannot modify header information - headers already sent by (output started at /w3/httpd/docs/mediawiki/LocalSettings.php:170) in /w3/httpd/docs/mediawiki/includes/WebResponse.php on line 38

Warning: Cannot modify header information - headers already sent by (output started at /w3/httpd/docs/mediawiki/LocalSettings.php:170) in /w3/httpd/docs/mediawiki/includes/WebResponse.php on line 38

Line 38 it's

public function header( $string, $replace = true, $http_response_code = null ) { header( $string, $replace, $http_response_code ); }

I appreciate a lot your help :-)
