Help = Basic user how to

So I have managed to install and configure ConQuest on Ubuntu 10.04

I have tried to add downloaded sample directly on the web gui but I am always faced with

500 Internal Server Error

This is the entry in the apache log:

[Fri Jan 04 13:54:48 2013] [error] [client 10.0.0.30] Premature end of script headers: dgate, referer: http://10.0.0.21/cgi-bin/dgate

Any suggestions??

Also where can I upload image files for automatic inclusion in the conquest database?

Thanks
