Hi all, I have Koha 3.04.04 installed on Ubuntu 10.04 and I'm getting the error Can't call method "subfield" on an undefined value at /usr/share/koha/lib/C4/Biblio.pm line 2835. on basically anything, Check In, Check Out, adding books and so on but even if there is an error, the operation seemingly completes successively. Now while I'm ready to go into production usage even with this error if despite it operations will be successfully done, but I would like to avoid having to fix at later date something that then turns out is a big problem. Also I have seen other posts detailing this bug. And most of them say that it's a problem with Marc to Koha mapping, and that I should check the mapping of the offending sub field, but how do I know WHICH sub field produces this error. Thanks in advance Maritime School Kotor -- View this message in context: http://koha.1045719.n5.nabble.com/Can-t-call-method-subfield-ERROR-tp4806073...
