[ic] trouble with demo

[j p]

Hi,
 I am loading interchange 4.6 and haven't got past getting the demo "contruct something". When I got to "check out", I get:

"
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, root@localhost and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

                          any ideas?

                      thanks, Jim
