More detail:
We are using a Win 2003 server.
Php 5.0.4 is installed and working on our main site. On the same machine but with a different physical path we have test site accessed via a non standard port.
Both were working, but on the test site we are experimenting with dompdf. It was in the process of trying to tweak this that php became broken on both sites. Then it was fixed (by altering php.ini) on the main site. However on the test site when we attempt to run ANY php we get
"No input file specified" as the only output.
I must reiterate: we are not using php as a CGI.
Can anyone help?
