Hi, I've noticed differences between English and French syspref: /installer/data/mysql/en/mandatory/sysprefs.sql /installer/data/mysql/fr-FR/1-Obligatoire/unimarc_standard_systemprefs.sql I've done a script which identified those differences. Variables available in 'en' but unavailable in 'fr-FR': 1. acquisitions 2. finescalendar 3. marcflavour - should be added to 'fr-FR' 4. opacmaintenance - should be removed (and in admin/systempreferences.pl) 5. opacmainuserblock - must be added to 'fr-FR' (that's from this syspref I've began noticing those differences) 6. opacuserjs 7. patronsperpage - should be added to 'fr-FR' 8. previousissuesdefaultsortorder - should be added to 'fr-FR' 9. sortbynonfiling - to be removed 10. specifyduedate 11. todaysissuesdefaultsortorder - should be added to 'fr-FR' Variables available in 'fr-FR' but unavailable in 'en': 1. amazondevkey - to be removed 2. authdisplayhierarchy - used in authorities/detail.pl and opac/opac-authoritiesdetail.pl 3. hidebiblionumber - to be removed (and in admin/systempreferences.pl) 4. readinghistory - used in several places: should be added to 'en'? 5. receivebackissues - to be removed (and in admin/systempreferences.pl) -- Frédéric
