front end editor won't load

the front end editor will not load. I normally don’t use front end but i tried following video instructions for building gallery and front end just won’t load. attached screenshot. For me the gallery video is hard to follow. I can follow better when there is an explanation. I am using a photo gallery i bought, but i like the look of the built in one. here is site. http://nitrokick.net
