I am running multiple wordpress blogs on the following setup:

Server 2008 R2; IIS 7.5; PHP 5.3.3; MySQL 5.0.7;

I upgraded my wordpress install from 2.9.2 to 3.0.2 (on 2 different sites) today and the upgrade went fine. I can serve .php pages without errors, log into the admin system etc. I can browse my blog by going directly to, but when I try to go to (without the index.php) I get he below 500 error.

I reset IIS, removed and re-attached the default document, but I am running out of ideas.

Please if anyone has a solution for this that would be great.

This is the 500 error I am getting:

Error Summary
HTTP Error 500.0 - Internal Server Error
The page cannot be displayed because an internal server error has occurred.

Detailed Error Information
Module FastCgiModule
Notification ExecuteRequestHandler
Handler PHP FastCGI
Error Code 0x00000000
Requested URL
Physical Path D:\\index.php
Logon Method Anonymous
Logon User Anonymous

Looks like it might have something to do with permalink redirects, I am using IIRF to do the redirects and not of them are working anymore anyone could see how that is related? – Maniac13 Dec 9 '10 at 22:07

Open your PHP.ini and look for the "error_log" value. Make sure it points to a file where the IIS worker process can write. Also check the "error_reporting" value and make sure it includes "E_ALL".

After that, open the file pointed at by the "error_log" value: it should contain more information about what broke.

Open IIS -> Selct Your web site -> Under IIS Section

Error Pages -> 500 -> Edit Feature Settings -> "Detailed Erros"

This how you will be able to see exact error and that might help you to resolve your isuse.

Best of Luck :)
