Recently my ISP switched our website to an IIS7.0 high availibility cluster. The website is running on PHP5.2.1 and I can only upload files (so no registry tweaks). I had tested the website before and everything seemed to be working, but now the checkout page fails with:

500 - Internal server error. There is a problem with the resource you are looking for, and it cannot be displayed.

As error messages go, this isn't very informative. I've tried:

ini_set('display_errors', 1);
ini_set('error_log', $file_php_can_write_to );

but both don't seem to do anything.

Anyone know how to get better debugging output?
