Just done a windows install of koha 3 (with strawberry perl) get the error below when adding books The following fatal error has occurred: Can't call method "fields" on an undefined value at G:/koha/prog/src/C4/Biblio.pm line 1923. Apache Server version: Apache/2.2.11 (Win32) Server built: Dec 10 2008 00:10:06 Koha 3.01.00.061 Koha DB 3.0100061 MySQL mysql Ver 14.12 Distrib 5.0.45, for Win32 (ia32) OS Windows NT ... 5.2 Build 3790 (Service Pack 2) x86 Perl 5.008009 Saw a similar post in the forum ( http://lists.katipo.co.nz/public/koha/2008-December/016248.html ) but no resolution ..
