500.19 error in IIS7 when an error occurs

Question

Setup: Windows 7, IIS7. I am working on an app that is being viewed through the local IIS server, not the built in debugging web server. So my app url is http://localhos

Answer 1

I had this same issue in IIS 8.5. The fix was to delete any entries in the web.config file (located in the root directory of the website) that referenced the custom error pages. The entries were created by the system when I had attempted to make changes to custom pages.
