Thread:Project:Support desk/Webresponse.phph Line 16 - Blank Page

It seems to be a quite common problem:

The error message I get from following the steps explained here is: "Warning: Cannot modify header information - headers already sent by (output started at /var/www/webXX/html/XXXYY/LocalSettings.php:1) in /var/www/webXX/html/XXXYY/includes/WebResponse.php on line 16"

The mentioned line 16 in the WebResponse.php is: header($string,$replace);

It all results in a blank page when saving any edit of any page:

URL: test.travel-namibia.com Mediawiki Version: 1.14.0 PHP-Version: 5.2.6-1+lenny9 MySQL: 5.0.51a

Any solution? (nope, upgrading is not a solution, as I get a bunch of even more severe erros when using 1.15 or 1.16)

Thanks Christian
