Run CGI Script from cgi-bin 500 error

[mwlake]

Hi All,
Most likely I missed something simple but I am having a real Headache getting a simple hello.cgi script to run from the cgi-bin/ folder of my domain.
Yes, Chmod is set 755, uploaded using ascii.

From command-line in ssh no syntax errors in script.

In my browser, when I type in the address field: http://www.domainname.com/cgi-bin/hello.cgi I always get 500 error - Internal Server Error. I assume ISPCP is blocking this for security reasons, the question is how to unblock.

ISPCP 1.0.0 Omega
build:20090225
Codename:Priamos

Hope someone can help
