Hey folks, I managed to get Koha mostly running one a single machine with a single IP address by using VirtualHosts and NameVirtualHosts in Apache. However, not everything works. Specifically, the Acquisitions and Circulation portions of the intranet give me Internal Server Errors. Examining Apache's error log gives me the following: If I attempt to go to circulation, I get: premature end of script headers in /home/httpd/cgi-bin/koha/circ/circulation.pl If I attempt to go to Acquisitions, I get 2 errors: Undefined subroutine &main::systemprefs called at /home/httpd/cgi-bion/koha/loadmodules.pl and Premature end of script headers: /home/httpd/cgi-bin/koha/loadmodules.pl I take it the premature end of script headers are the standard errors that happen when a web-script fails to produce a good page. The problem is that I don't know how to get more information than that. Has anyone seen this before? Thanks, Rob __________________________________________________ Do You Yahoo!?
