Ok , the problem is solved now . The failure was because of the plugin https://github.com/ldjamison/koha-plugin-room-reservations which use the same table bookings as also the new feature https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=29002 Already an issue is raised : https://github.com/bywatersolutions/koha-plugin-room-reservations/issues/57 From: gveranis@dataly.gr <gveranis@dataly.gr> Sent: Δευτέρα, 4 Δεκεμβρίου 2023 10:01 πμ To: 'koha@lists.katipo.co.nz' <koha@lists.katipo.co.nz> Subject: Koha 23.11 circulation problem Hi all, After upgrade to 23.11 we have a problem on circulation module. When trying to check-out an item on intranet-error.log we get "DBIx::Class::Storage::DBI::_dbh_execute(): DBI Exception: DBD::mysql::st execute failed: Unknown column 'me.booking_id' in 'field list' at /usr/share/koha/lib/Koha/Objects.pm line 317" Can anyone help ? I search to Bugzilla but didn't find any known bug on that. Thanks, George Veranis
