apache2 upgrade broke wordpress install

[Jerome Lacoste <jerome@coffeebreaks.org>]

Hi,

I have a wordpress blog on an apache 1.3 powered sarge box.
I am trying to upgrade to apache2 but some things don't work.

In particular the wordpress (using php4) blog now return empty pages,
while for example the bbclone statistics page still work.

See http://www.coffeebreaks.org/~jerome/wordpress/index.php for the
blog. Click on stats for the bbclone page.

E.g. of an apache2 log from a browser reading my blog page:

193.212.132.34 - - [06/Oct/2004:11:35:26 +0200]
"GET /~jerome/wordpress/index.php HTTP/1.1" 200 - "-" "Mozilla/4.0 (comp
atible; MSIE 6.0; Windows NT 5.1; Maxthon; .NET CLR 1.1.4322)"

Notice the empty 'size' field. 

Same page loaded from apache1

12.215.220.247 - - [03/Oct/2004:11:10:00 +0200]
"GET /~jerome/wordpress/index.php HTTP/1.1" 200 13541

Here one can see that the size element is correct.

Of course nothing particular shows in the error logs.

I am at anyone's disposal to switch server version or to allow
server-info / server-status pages to be viewed from outside in order to
help me troubleshoot this problem.
