I have a koha system 3.16.4 running on ubuntu. I am trying to setup "fine" function. When bin/cronjobs/fines.pl executed, I got the following error. DBD::mysql::db selectrow_array failed: Table 'kohadata.systempreferences' doesn't exist at /usr/share/koha/lib/C4/Context.pm line 563. DBD::mysql::db selectrow_array failed: Table 'kohadata.systempreferences' doesn't exist at /usr/share/koha/lib/C4/Context.pm line 563. DBD::mysql::db selectrow_array failed: Table 'kohadata.systempreferences' doesn't exist at /usr/share/koha/lib/C4/Context.pm line 563. DBD::mysql::db selectrow_array failed: Table 'kohadata.systempreferences' doesn't exist at /usr/share/koha/lib/C4/Context.pm line 563. DBD::mysql::st execute failed: Table 'kohadata.issues' doesn't exist at /usr/share/koha/lib/C4/Overdues.pm line 140. Can't use an undefined value as an ARRAY reference at /usr/lib/perl5/DBI.pm line 2064. Does it mean something wrong with my database? Thanks, Justin
