One can set invalid values like "0,00" to the syspref ExpireReservesMaxPickUpDelayCharge and it will cause the cronjobs/holds/cancel_expired_holds.pl to fail: > Argument "0,00" isn't numeric in numeric gt (>) at [...] Expected behaviour: When setting the syspref in the staff interface Koha should should disallow setting invalid values.
I found out that 0.00 is invalid value, too because 0 fees cannot be set. 0 works however.
