[Mediawiki-l] cannot change LocalSettings.php

[Ken Avonts]

Thanks for your reply.

There's no accidentally inserted whitespace whatsoever. That's what makes 
this all so weird... Maybe your suggestion about the BOM is a good clue. I'm 
using Windows Notepad to edit the php-files. I cannot find an option about 
this BOM. Should I use another text-editor instead?

Could it have something to do with FileZilla? Maybe FileZilla inserts 
something...
