I've uploaded my new site but I still see the old version, why is this?

The most common cause of web pages not updating once you have uploaded new
files to your hosting space is Caching. Caching is used widely across the
Internet to cut down the amount of time it takes to request information. It
works by keeping a temporary copy of information that has been requested
locally for a defined amount of time.

To stop receiveing the cached page you will need to press ctrl+f5 - this will refresh the root page.
