[Mediawiki-l] Touching LocalSettings.php break 1.9.2

[kent sin]

I just download the current 1.9.2

After setup, I move the LoalSettings.php and play around without problem.

However, if I open the LocalSettings.php with NotePad and save it.
(not changing anything), The site just return blank.

I can delete the file and generate a new one. Then mediawiki works again.

Can anyone help me?
