Website recently completely stopped working

Hi folks, I don’t know if anyone can help. I have recently done a lot of work on the website http://www.apricotcentre.co.uk Unfortunately i did many things, and something i did has stopped things working at all. Basically the index.php page is not loading up. It keeps repeatedly trying but never loads. I did a reroute from….. aaaaaaah I may have worked out what i’ve done. I rerouted from an index.html address…. to apricotcentre.co.uk … but no that doesn’t make sense as even putting http://www.apricotcentre.co.uk/index.php doesn’t load…..

Any thoughts or ideas..
