I am trying to test, if Koha can work for us. We have imported the Danmarc2 format instead of marc21, and after some work with the Koha db- Marc linking, the Marc Check is finally OK. BUT: Adding the Biblio seems to be OK - but when I after the Biblio is added is transfered to the "New Item" screen, there is a failure when I press "Add Item" The browser changes its url to http://admin.koha.boegenielsen.dk/cgi-bin/koha/acqui.simple/additem.pl and responds with a 500-error "Internal Server Error". The koha-error-log: [Thu Aug 5 16:28:11 2004] [error] [client 194.192.135.47] Premature end of script headers: /usr/local/koha/intranet/cgi-bin/acqui.simple/additem.pl Fields below 010 do not have subfields at /usr/local/koha/intranet/modules/C4/Biblio.pm line 909 [Thu Aug 5 16:29:41 2004] [error] [client 194.192.135.47] Premature end of script headers: /usr/local/koha/intranet/cgi-bin/acqui.simple/additem.pl /Thomas Bøge
