Have you tried looking at the HTML source of the page you get?

My guess is that you get a 500 error because you get PHP errors in
the middle of header info, and this makes for bad header syntax.

To see the errors, force header output *before* doing whatever it
is that draws errors.

I don't think the problem deals with header syntax ...
My php test page is as easy as :

<?php
$data = 0/0;
show/hide quoted text

I would like "PHP Warning: Division by zero in C:\inetpub\wwwroot
\Catalogues " beeing printed on the return page ... Instead of it, I
got 500 error, even with display_errors=On.
I have tested it on a "standard" LAMP server, and it works (error is
printed) ...
I also tried to process the test page directly on a console (using
"php -f mypage.php"), and the warning is well printed in the console.
So the problem seems not to come from the php interperter.

Zend is in a full default configuration state. The only param I have
changed is the display_errors config.
I tried also with PHP manualy installed from the official binaries (so
without the zend package). The problem is exacly the same ...

I am using a clean IIS7 server, and have PHP FastCgi module mapping to
the websites needing PHP support.

It may come from IIS7 or FastCGI. But where ? That is the question ...

Any more ideas ?

Guillaume

Found the solution :

You would need to set system.webServer/httpErrors/errorMode to
Detailed to do this - default is DetailedLocalOnly so as not to expose
extra information to remote clients. The following appcmd command
will achieve that.

%windir%\system32\inetsrv\appcmd.exe set config -
section:system.webServer/httpErrors -errorMode:Detailed
