Hello all, I have just finished an upgrade from 3.2.10 to 3.4.3 and after the upgrade, ran the remove_items_from_biblioitems.pl script. I had the following error repeatedly - use of uninitialized value in pattern match (m//) . After the script completed, I re-indexed zebra and ran a search from the OPAC, I got results but every biblio in all the results always say item is not available, despite the items being displayed in the details page. Also circulating books give the error - "Can't call method "subfield" on an undefined value at /usr/share/koha/lib/C4/Biblio.pm line 2835." even though checking the patron's record later shows the book has been successfully checked out. Is there a way i can verify that the items were successfully removed from biblioitems? One thing with this installation is that the Marc - Koha mappings are not the standard Koha ones. the install has been coming from 2.2.9 and I had to modify record.abs to get zebra to work. Any tip/suggestion to get the problem solved will be appreciated.
