I recently reported that we'd started to get internal server errors when looking at ISBD detail and making a hold when in the OPAC. Jonathan Druart asked if I'd run misc/maintenance/ search_for_data_inconsistencies.pl to catch potential problems with our data. There were numerous errors with respect to home branch and/or holding branch which I corrected. We've run search_for_data_inconsistencies.pl again and no problems are reported. We're still getting internal servers errors when looking at ISBD detail and making a hold when in the OPAC. Is there anything else I can check? We've also seen that the plack-error.log has a continuously generated error: DBD::mysql::db selectrow_array failed: Unknown column 'LOST' in 'field list' [for Statement "SELECT LOST from items where itemnumber = ?"] at /usr/share/koha/lib/C4/Items.pm line 1229. -- Paul Leman
