I have encountered a layout issue on the iPhone after installing the multi site feature. When I view the home page http://www.paolodipasquale.co.uk on an iPhone it doesn't stretch to fit the screen, however single pages like "About Me" and "Portfolio" do. The theme I am using is Twenty Eleven and this appears to work fine on the iPhone when I create a new site for example http://www.paolodipasquale.co.uk/test/.
This has me completely puzzled. Can anyone help?
