Internal Server Error 500 - CF9 on Win2k12 x64

[tomtheone]

Hi all,

I have installed the cf-google-authenticator on our win2k12 x64 cf9 server.

I received following error message after clicking "Generate" on sample/sample_generate.cfm:

---

Invalid CFML construct found on line 126 at column 80.

ColdFusion was looking at the following text:
[

The CFML compiler was processing:

A script statement beginning with public on line 126, column 5.

The error occurred in D:\PATH\authenticator\authenticator\GoogleAuthenticator.cfc: line 126
125 : 
126 :     public string function generateKey (required string password, array salt = [])
127 :     {
128 :         if (arrayLen(salt) == 0)

I changed following in authenticator\GoogleAuthenticator.cfc:

124 :    force_empty_salt = [];
125 :
126 :    public string function generateKey (required string password, array salt = force_empty_salt)

And voilà, i received the QR code.
