[Mediawiki-l] cannot change LocalSettings.php

[Ken Avonts]

Hello!
The installation was succesfull. After enabling image uploads, and thus only changing false into true, de LocalSettings.php doesn't work anymore. I get this error: 

Warning: Cannot modify header information - headers already sent by (output started at /opt/www/avontsk/web/www.derepubliek.eu/vvp/wiki/LocalSettings.php:1) in /opt/www/avontsk/web/www.derepubliek.eu/vvp/wiki/includes/WebResponse.php on line 9


Only the original LocalSettings.php seems to work. It's strange that changing just one option makes the wiki go crazy.

Thanks!
