Site Preview and Coldfusion

[rokit13]

All of a sudden I cannot preview the sites that use coldfusion. The pages come up blank and no code is working. I tried a test.html file on the server and that shows up.

The sites work fine when going through the URL but anything previewed through the site preview link doesn't work.

The site preview and coldfusion had been working before today and a restart of the server does not fix it.

I am not sure how to proceed, any help would be appreciated.
