No redirect on new server

Hi,

I’m migrating my website to a new server. On the old web server the redirection plugin worked flawlessly. On the new server it’s not working at all. I’m wondering if there’s something simple missing in the server configuration that might be getting in the way.

When I try to visit a redirect url, I just get a blank page, no error, it just doesn’t load anything.

Here’s a sample: http://vahumanities.org/newsletters/

Can you point me in the right direction?
