Hello Koha Community! Why does the problem occur on a fresh install? 21.11 Unimarc DBD::mysql::db do failed: Cannot add or update a child row: a foreign key constraint fails (koha_koha3.repeatable_holidays, CONSTRAINT repeatable_holidays_ibfk_1 FOREIGN KEY (branchcode) REFERENCES branches (branchcode) ON DELETE CASCADE ON UPDATE CASCADE) at /usr/share/koha/lib/C4/Installer.pm line 574. Good Luck! Igor A. Sychev Tomsk Polytechnic University https://lib.tpu.ru
