If you rally run php with fastcgi or fcgid then some setting is not correct in your installation.
Is the beginning of the first post what phpinfo is saying?
(because the ispcp php.ini do not allow the command phpinfo :-)
On my Debian 5 with ispcp 1.0.7 it looks like this:
Code:

You may need to check your fastcgi/fcgid configuration.
