Move to new hosting application/x-httpd-php

Ok, I had my WAP site working perfectly on my old orchardhosting host, I was using cpanel to control subdomains (mobile.commusoft.co.uk - which takes you to index.php forwarding you to wmlloginform.php)

Now I have moved to a VPS host using plesk I cannot get the WAP site to work at all.
when you to go the above web address it asks you to download the page and gives me this : application/x-httpd-php

I have no idea why, I asked my host they do support WAP, anyone got any idea why this would now not work?

I think I have found my error, it seems that I havent removed my cahe and other offline files..... damn web browsers!!
