I prefer "ls -ld" myself.

Never remove it. It is only created by the web server at startup or log rotation time. So now you need to restart the apache to get it back.

Just open a spare terminal and run:

  tail -f /var/log/httpd/error_log

Well, it is helpful to know. if the CGI script tries to write any data to files,
if it runs as a different user it will need different permissions on the files.

I would be tempter to wrap the CGI script in a shell script.
Suppose your script is named foo.py. 

You can move the script to foo-py and make a shell script called "foo.py" looking like this:

  #!/bin/sh
  exec 2>>/home/nikos/cgi.err.out
  echo "$0 $*" >&2
  id >&2
  env | sort >&2
  set -x
  exec /full/path/to/foo-py ${1+"$@"}

and make sure it, like the original, is readable and executable:

  chmod a+rx foo.py foo-py

Make sure cgi.err.out is publicly writable (in case the apache is
not running the CGIs are you):

  chmod a+w cgi.err.out

Then:

  tail -f cgi.err.out

in a spare window.

Then try the script.

It should transcribe information about the script's user and
environment and also catch errors.

This should help in debugging.
