One suggestion I have for your demo content is to make sure you use // instead of http:// when linking content in it. One example for the single page theme would be you have

@import url(http://fonts.googleapis.com/css?family=Open+Sans:400,600,700,300);

in the custom CSS section but should use

@import url(//fonts.googleapis.com/css?family=Open+Sans:400,600,700,300);
