For some unknown reason www.sarumscaffolding.co.uk is not showing the correct home page. If you go to the website you will se what I mean. If you open another page and then link back to the home page it is correct but shows as sarumscaffolding.co.uk/index.php. when the page is sarumscaffolding.co.uk/index.html the page is weird but all the other pages are correct at *html.

Any idea what is causing this.
