Possibly you are viewing an older version of your website from your local machines cache files. The solution is to clear out your Temporary Internet Files. You can do this in Internet Explorer by:

  1. Clicking on Tools > Internet Options
  2. Go to the General tab, Temporary Internet Files.
  3. Click on the Delete Files button.

If you haven't done this in a while, it may take some time. Once you open your website, hold down the Ctrl key and press the refresh icon simultaneously. This will also help load the latest version from your host server.
