CF11 cfc gives 500 error but cfm is fine

Question

We are testing our cf code which all works fine on a CF9 Windows Server 2008 machine but we are going to migrate to a CF11 Windows 2012 R2 machine. We have a test machine setup and all the code moved over and so far the cfm pages seem to work fine as well as the Application.cfc page but when we call a cfc via AJAX or we visit the cfc methods directly we get a 500.0 error Application could not be found.
Anybody else run into this?

Answer 1

I will do both as separate messages with some info redacted with XXXXXX. The Application.cfc in the root directory is below.
