white blank page

hello,
I have a site http://www.sheyvr.com, which shows a blank white page when typed in my search bar of my browser and the url changes to http://www.sheyvr.com/defaultsite. I can’t see any thing.
I even uninstalled wordpress and started to build my site from the start still facing the same problem. When i visit the site from my hosting it is displayed but when i search it in the browser it doesn’t.
