Can you check the PHP error log to see what's actually happening when the empty

My Problem is the same, I tried to reinstall Mediawiki but it's still the same.
The error log shows:

Warning: Cannot modify header information - headers already sent by (output
started at c:\Programme\PHP\root.php:8) in
C:\Inetpub\Mainroot\LGHWiki\includes\WebResponse.php on line 9

And this message appears 6 times. What can I do? We're using the latest version
of Mediawiki and we also have the latest PHP version. The Webserver is running
on Windows 2000.

Timo, do you have PHP configured to include a particular file at the start of
every script (auto_prepend_file in PHP.ini)? It seems that "root.php", which is
nothing to do with MediaWiki, is being executed, and it's producing some output
which blocks us sending headers.

This may or may not be the same problem that Markus is having.

I have opened a support ticket at my webhoster to get the information out of the
log files. It's a shared webhosting environment, so I think only the provider
has access to it... Or is it possible for me as a client to look into these
logs?! Where are they normally stored?

Yes, you can get the vaule. In a file (say info.php), put in this line
<?php phpinfo(); ?>
and then access that page from your browser. Check what value it has for
auto_prepend_file (just seach for that string)

My provider (all-inkl.com) has fixed the problem: it was a problem with zend
optimizer. They have installed an update and now it works fine again. Thanks for
your help!
