Membership Plugin Signup form not working

For some reason when you go to my signup page it shows the word Empty where the form should be. I have one subscription setup tied into one level called "member" and I set up the signup page called "Sign Up" with the shortcode in it. I have no idea why it isn't working.

Here is a link to the page:
