FastCGI Error while trying to access admin area on IE8

[Tino]

Hi all,

I've recently installed CMSMS 1.6.6 onto a client's webspace and everything appeared to work fine. However I can't access the admin area through IE8, instead getting the following error:

FastCGI Error
The FastCGI Handler was unable to process the request.
--------------------------------------------------------------------------------

Error Details:

•Error Number: 13 (0x8007000d).
•Error Description: The data is invalid.
HTTP Error 500 - Server Error.
Internet Information Services (IIS)

If I access it through Firefox I have no problems at all.

I'm using a different host from my usual one and, as this is the first install of CMSMS I have made with them, I assumed it must be something at their end. However having contacted them their response is that if it's working through Firefox, it must be a problem with the code.

I've done some searching and have come across a few threads where something similar is mentioned, but never with a solution.

Can someone please help?

Many thanks,
Tino

Have you looked in the system info page to see if you have any yellow ! or red X?...

[Tino]

I have one yellow ! (PHP register_globals (register_globals): On (True)) and one red x (config_file: 0666 Failure. config.php writable. It is more safe if you change permission to read-only)

I will change teh config.php permissions just now, but is the PHP error likely to be causing my problem?

Many thanks,

Maybe it has to do with using IIS which I have no idea about...

[Tino]

I'm not too familiar with IIS either - would this be something that would need sorted at the server/host end?

Can anyone else shed further light on this?

Many thanks,
