Who is the hosting provider?

Does your hosting allow installing of php into virtual folders.

Some webhosting providers have a setting enabled that disalows the installation of PHP scripts inside a virtual folder, In your case  I call www.mysite.biz.nf (here I use a subdomain)

I may have read it wrong but you say a subdomain, I am just checking with you that you are not trying to installe it to a folder inside your root I.E http://www.yourdomain.com/dolphin/ if your trying to install into a folder as above then this is called a virtual folder, as I said some hosts dont allow this.

If it is an actual subdomain I.E http://dolphin.yourdomain.com then thier should be no problem however you would need to login via FTP into your subdomain if the subdomain is not accessable via your root FTP.

Also please attach your screen caps to the post they are to small to see the URL and from my eyesite your URL looks funny a bit strainge
