Can't move past wizard screen

On staging - on the wizard screen: http://qa-vumi.za.prk-host.net/wizard/create/

I provide a conversation name and description.
I pick 'dialogue' as the conversation type
I select "set up a new channel" and pick a channel
I click the 'save' button
Instead of being directed to the survey builder, I remain on the wizard screen: http://qa-vumi.za.prk-host.net/wizard/create/ and get a blank page
