Well, following the advice of the list I decided to upgrade from 1.2.3 to 2.2.3, via 2.0.2 The upgrade from 1.2.3 went without a hitch and 2.0.2 seemed to run fine. Since I wasn't planning to use MARC I answered "N" to the question about which version of MARC I should use during the upgrade. I then went to the System Parameters section and set "Use MARC" to "0". All seemed fine. I then upgraded to 2.2.3 and the problems started. Again I answered "N" to the MARC question. The upgrade seemed to run successfully, but when I sent to the catalogue to do a search, I got an "internal server error". The log said [Sun Jul 31 00:48:39 2005] [error] [client 192.168.1.3] Can't use an undefined value as a HASH reference at /usr/local/koha/intranet/modules/C4/SearchMarc.pm line 255., referer: http://loki:8080/cgi-bin/koha/search.marc/search.pl?type=intranet [Sun Jul 31 00:48:39 2005] [error] [client 192.168.1.3] Premature end of script headers: search.pl, referer: http://loki:8080/cgi-bin/koha/search.marc/search.pl?type=intranet Looking at this I thought that it seemed to be looking for something to do with MARC so I went to the Parameters section to check on the system settings..... and nothing was visible. Can anyone help? Is it something to do with my not using MARC? Should I roll back to 1.2.3 and then choose one of the two MARC settings instead of "N". I really don't know anything about MARC (but I want to use Z39.50 searching... do I need to enable MARC to use this?) I'm running Fedora Core 2, with perl 5.8.3 Any pointers greatfully received.
