Here are to URLs that address the same set of web pages. The first is hosted on the work in progress section of my own website hosted by 123-reg; the second is hosted on its ultimate destination with BT.
As one navigates from page to page on the first, the transition is seamless, as indeed it should be. When one navigates from page to page on the site as hosted by BT however the page background fills the entire screen before the new page's content appears. Does anyone know why this happens on the BT server, please, and what can be done to remedy it?
