HTTP Error 500.19 – Internal Server Error

The requested page cannot be accessed because the related configuration data for the page is invalid

  1. Go to “C:\Windows\System32\inetsrv\config”. [Note: you need to have admin rights to modify applicationHost.config file]
  2. Now open applicationHost.config
  3. Look for “modules” or “handlers” based on error message
  4. Change the overrideModeDefault attribute from “Deny” to “Allow”. In my case it is with handlers. So I modified it accordingly.

<section name=”handlers” overrideModeDefault=”Allow” />
