Dear List members, We have a KOHA 3.06 Marc21 version, where we encounter a following problem: Any Authority search for existing records results in a message: "Software error: Can't call method "raw" on an undefined value at /usr/share/koha/lib/C4/AuthoritiesMarc.pm line 307. For help, please send mail to the webmaster..." While searching for specially constructed un-existing term gives ordinary result: "No results found". Also any biblio entry (via cataloguing) with authority fields (eg. 100, 700, etc.) on saving the record gives a similar message: "Software error: Can't call method "raw" on an undefined value at /usr/share/koha/lib/C4/Search.pm line 269." While saving the same entry without field 100 results in normal saving of a record. We have re-indexed Zebra, then restored the last working backup of a database (made 3 days ago), but the same problem remains. We saw several similar (but different) discussions in a list, but no real results. This happens both in intranet and OPAC: http://opac.sciencelib.ge/ Any help would be appreciated.
