errors

We have Drupal 7 up and running on Windows IIS 7. But we are getting some errors right now that we are finding difficult to troubleshoot (they are not site wide, just specific to editing content types, and editing specific pieces of content).

These are internal server errors, but we have been unable to log these or get a more verbose error message to display. We've edited the php.ini and our web.config, but nothing seems to work.

How are people logging these in general, or how would you to get the a verbose error to display.

Thanks for your help
