Upfront not showing Customise options

I installed this theme. Regardless of whether i use Safari, Chrome or Firefox I am not able to see the widgets / element modifier that is in the tutorial.
Whenever I select "Customise" I am taken to the address http://www.soulfulearning.co.nz/?editmode=true and if i select on anything - nothing happens - is there a plugin i need or an extension or some configuration i have missed?
