When I try to upgrade the schema it doesn't go past 19.06.00.005. It throws the following error: Update errors : ISBN_RANGE_MESSAGE is set to [] but that file does not exist! Trying to use the default locations at /usr/share/perl5/Business/ISBN.pm line 87. Can't use string ("- id: 165 selector: #coverflo"...) as an ARRAY ref while "strict refs" in use at /var/lib/koha/library/plugins/Koha/Plugin/Com/ByWaterSolutions/CoverFlow.pm line 377.
