Yes, the previous problem was solved, indeed... I do not understand why I have so many problems installing koha,.. maybe the last years I was too used to Joomla! installations :D So the challenging koha that its concept I so much admire and embrace makes me face another problem. Trying to add a MARC record, (I retrieved its data from a z30.50 server, but that does not matter, I think) and then I am getting an error page (http://localhost:8080/cgi-bin/koha/cataloguing/additem.pl) Its contents are: " Koha error The following fatal error has occurred: Can't call method "append_fields" on an undefined value at /usr/local/share/perl/5.10.0/MARC/File/SAX.pm line 95. at /usr/local/lib/perl/5.10.0/XML/LibXML/SAX.pm line 64 at /usr/local/share/perl/5.10.0/MARC/File/XML.pm line 443 Apache Server version: Apache/2.2.9 (Debian) Server built: Jun 21 2008 10:35:35 Koha 3.00.00.094 Koha DB 3.0000094 MySQL mysql Ver 14.12 Distrib 5.0.51a, for debian-linux-gnu (i486) using readline 5.2 OS Linux sangre 2.6.25.9xx6-costis07 #1 SMP PREEMPT Wed Jul 2 02:35:38 EEST 2008 i686 GNU/Linux Perl 5.010000 " The laste contens of /var/log/koha/koha-error_log are [...] [error] [...] [...] addbiblio.pl: INDEXING :orignew at /usr/share/koha/lib/C4/Biblio.pm line 2319., referer: http://localhost:8080/cgi-bin/koha/cataloguing/addbiblio.pl?biblionumber=0&z3950=1&frameworkcode=BKS&breedingid=1 [...] [error] [...] [...] addbiblio.pl: INDEXING :1 at /usr/share/koha/lib/C4/Biblio.pm line 2319., referer: http://localhost:8080/cgi-bin/koha/cataloguing/addbiblio.pl?biblionumber=0&z3950=1&frameworkcode=BKS&breedingid=1 [...] [error] [...] [...] addbiblio.pl: INDEXING :ocip at /usr/share/koha/lib/C4/Biblio.pm line 2319., referer: http://localhost:8080/cgi-bin/koha/cataloguing/addbiblio.pl?biblionumber=0&z3950=1&frameworkcode=BKS&breedingid=1 [...] [error] [...] [...] addbiblio.pl: INDEXING :20 at /usr/share/koha/lib/C4/Biblio.pm line 2319., referer: http://localhost:8080/cgi-bin/koha/cataloguing/addbiblio.pl?biblionumber=0&z3950=1&frameworkcode=BKS&breedingid=1 [...] [error] [...] [...] addbiblio.pl: INDEXING :y-gencatlg at /usr/share/koha/lib/C4/Biblio.pm line 2319., referer: http://localhost:8080/cgi-bin/koha/cataloguing/addbiblio.pl?biblionumber=0&z3950=1&frameworkcode=BKS&breedingid=1 [...] [error] [...] [...] addbiblio.pl: INDEXING :ddc at /usr/share/koha/lib/C4/Biblio.pm line 2319., referer: http://localhost:8080/cgi-bin/koha/cataloguing/addbiblio.pl?biblionumber=0&z3950=1&frameworkcode=BKS&breedingid=1 [...] [error] [...] [...] addbiblio.pl: INDEXING :SR at /usr/share/koha/lib/C4/Biblio.pm line 2319., referer: http://localhost:8080/cgi-bin/koha/cataloguing/addbiblio.pl?biblionumber=0&z3950=1&frameworkcode=BKS&breedingid=1 [...] [error] [...] [...] addbiblio.pl: INDEXING :pc15 2006-07-19 to SSCD at /usr/share/koha/lib/C4/Biblio.pm line 2319., referer: http://localhost:8080/cgi-bin/koha/cataloguing/addbiblio.pl?biblionumber=0&z3950=1&frameworkcode=BKS&breedingid=1 [...] [error] [...] [...] addbiblio.pl: INDEXING :jp00 2006-07-26 CIP recd at /usr/share/koha/lib/C4/Biblio.pm line 2319., referer: http://localhost:8080/cgi-bin/koha/cataloguing/addbiblio.pl?biblionumber=0&z3950=1&frameworkcode=BKS&breedingid=1 [...] [error] [...] [...] addbiblio.pl: INDEXING :jp20 2006-07-26 to subj at /usr/share/koha/lib/C4/Biblio.pm line 2319., referer: http://localhost:8080/cgi-bin/koha/cataloguing/addbiblio.pl?biblionumber=0&z3950=1&frameworkcode=BKS&breedingid=1 [...] [error] [...] [...] addbiblio.pl: INDEXING :jp03 2006-07-26 at /usr/share/koha/lib/C4/Biblio.pm line 2319., referer: http://localhost:8080/cgi-bin/koha/cataloguing/addbiblio.pl?biblionumber=0&z3950=1&frameworkcode=BKS&breedingid=1 [...] [error] [...] [...] addbiblio.pl: INDEXING :aa05 2006-07-27 at /usr/share/koha/lib/C4/Biblio.pm line 2319., referer: http://localhost:8080/cgi-bin/koha/cataloguing/addbiblio.pl?biblionumber=0&z3950=1&frameworkcode=BKS&breedingid=1 [...] [error] [...] [...] addbiblio.pl: INDEXING :1 at /usr/share/koha/lib/C4/Biblio.pm line 2319., referer: http://localhost:8080/cgi-bin/koha/cataloguing/addbiblio.pl?biblionumber=0&z3950=1&frameworkcode=BKS&breedingid=1 [...] [error] [...] [...] addbiblio.pl: INDEXING :1 at /usr/share/koha/lib/C4/Biblio.pm line 2319., referer: http://localhost:8080/cgi-bin/koha/cataloguing/addbiblio.pl?biblionumber=0&z3950=1&frameworkcode=BKS&breedingid=1 [...] [debug] mod_deflate.c(619): [...] Zlib: Compressed 37993 to 5966 : URL /cgi-bin/koha/cataloguing/additem.pl, referer: http://localhost:8080/cgi-bin/koha/cataloguing/addbiblio.pl?biblionumber=0&z3950=1&frameworkcode=BKS&breedingid=1 [...] [error] [...] [...] additem.pl: Can't call method "append_fields" on an undefined value at /usr/local/share/perl/5.10.0/MARC/File/SAX.pm line 95. at /usr/local/lib/perl/5.10.0/XML/LibXML/SAX.pm line 64, referer: http://localhost:8080/cgi-bin/koha/cataloguing/additem.pl?biblionumber=1&frameworkcode=BKS [...] [error] [...] [...] additem.pl: at /usr/local/share/perl/5.10.0/MARC/File/XML.pm line 443, referer: http://localhost:8080/cgi-bin/koha/cataloguing/additem.pl?biblionumber=1&frameworkcode=BKS What could I do to solve this problem?
