Hello Koha community, a few days ago I upgraded a Koha package system (UNIMARC flavour) from 3.6 to 3.12: I really like the 3.1x series and everything went quite smooth except some links between bibliographic and authority records being lost. Now if I go to More › Authorities and search the authorities by type, I get the expected search results but only the records belonging to the "bundled" italian auth types are correctly linked to biblios in the "Used in" column. I have created two custom authority types in the 3.6 system but according to 3.1x (the problem occurs in 3.10 and 3.12, not sure about 3.8) they are all Used in 0 biblio(s). I was aware of the warning for UNIMARC libraries upgrading to 3.10 and I manually replaced non-UNIMARC values found here http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=3087, restarted Zebra, even did a full reindex, but no success. I quickly checked some data involved in the linking within auth_header and biblioitems tables (like biblionumbers, biblioitemnumbers and $9 in the marcxml fields) and they seem to match with the ones in 3.6. I've been scratching my head for some days and tweaked some more the Zebra files but I had no luck, I also ran link_bibs_to_authorities.pl, and enabled the CatalogModuleRelink and LinkerKeepStale sysprefs... but again, no success. :) Could you help me please? Obviously I can provide additional info if needed, just ask! Thank you very much.
