can't create users or view/edit on site

[Lanny Baron]

Hi,
The logs are telling me: 

[Thu Jan 31 18:20:23 2002] [error] [client 216.126.78.90] Premature end of 
script headers: /www/data/freeside/edit/cust_main.cgi
Can't do setuid
[Thu Jan 31 18:21:14 2002] [error] [client 216.126.78.90] Premature end of 
script headers: /www/data/freeside/browse/part_svc.cgi 

What is causing this? 

Thanks,
Lanny
