Hello, I don't remember exactly but I'm upgrading from Koha 20.11 <https://koha-community.org/koha-20-11-15-released/> to Koha 21.05 <https://koha-community.org/koha-21-05-11-released/>. Install English langauge and I did not change anything. I think the problem is due to my use of UNIMARC But my country use UNIMARC
Maybe I would help to run misc/batchRebuildBiblioTables.pl or other and repair mappings? Or how else should I mapping biblionumber? Thanks for the help _______________________________________________ Koha mailing list http://koha-community.org [email protected] Unsubscribe: https://lists.katipo.co.nz/mailman/listinfo/koha
