Hi, I tried upgrading database created under Koha version 3.02.00.004 to version 3.06.3 and I get the following errors. Update errors : * [Fri Feb 24 11:52:26 2012] updatedatabase.pl: DBD::mysql::db do failed: Duplicate column name 'privacy' at /usr/share/koha/intranet/cgi-bin/installer/data/mysql/updatedatabase.pl line 3997. * [Fri Feb 24 11:52:26 2012] updatedatabase.pl: DBD::mysql::db do failed: Duplicate column name 'privacy' at /usr/share/koha/intranet/cgi-bin/installer/data/mysql/updatedatabase.pl line 3998. ... After database upgrade is done, I get the following error in web browser: Software error: Can't call method "delete" on an undefined value at /usr/share/koha/lib/C4/Auth.pm line 717. ... Any tips to solve this issues would be greatly appreciated. Thanks! -- Cheers, Dhiru
