Hi Since two days I am receiving the following unwanted e-mail from my demo installation (running Koha 19.05.00) every hour: ################################## Subject: Cron <root@vmi47659> cd / && run-parts --report /etc/cron.hourly /etc/cron.hourly/koha-common: UseTransportCostMatrix set to yes, but matrix not populated at /usr/share/koha/lib/C4/HoldsQueue.pm line 193. ################################## But in fact system preference "UseTransportCostMatrix" is NOT set to yes: mysql> select value from systempreferences where variable="UseTransportCostMatrix"; +-------+ | value | +-------+ | 0 | +-------+ 1 row in set (0.00 sec) What does it mean and how can I prevent getting this unwanted e-mail?
