FMS fails PHP Custom Web Publishing test

Just installed FMS 9, (previously had from FMS 8).

I am trying to access FMServer_Sample.fp7 in Safari 3.0.4. via the PHP test from the FileMaker Server 9 Technology Tests. I am getting the following error:

Safari can’t open the page.

Safari could not open the page “http://192.168.X.X/fmi-test/phptest.php?lang=en&server=.local” because the server stopped responding

I am trying to access from a local machine. On the XServe that hosts the FMS 9 databases, Web services show as being enabled. In the FileMaker PHP Site Assistant I also get the error, "Connection failed. Please check server address.

I can access FileMaker Server Admin console and it shows FMServer_Sample.fp7 as being enabled for PHP.

I think this is actually a web server issue.

How can I test the XServe web server?

Thanks I am very new to php etc.
