In overdue notice for the option "print" we use a template containing html. After running the overdue_notices cron job: > sudo perl /usr/share/koha/bin/cronjobs/overdue_notices.pl -t -v -html /tmp a message is presented by the system "The following terms were not matched and replaced: html, div, etc...". It seems like the system confuses the "<< >>" enclosed text with the html components. Nothing from the template is added to the generated html file. This bug is exactly the same as this bug fixed in 2013: https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=10720 You can also find it well documented in the commit here: https://gitlab.deichman.no/digibib/Koha/commit/394be84dcd65a4569d0467bc12b99dbd6341fc43
