[Mediawiki-l] Output Error

[大格]

Hello to All,

I have done some modification on the DefaultSettings.php and
DefaultSettings.php.bak, and right now my wiki site can't work as usual and
when I typed the link to my wiki, it displays some information as following:


*Warning*: Cannot modify header information - headers already sent by

Does some one know the reason and what modification should be made to make
it run as normal?

Thank you.
