It seems that the file fr-FR-staff-prog.po contain character that are not escaped on line 17596. In the template memberentrygen.tt, line 1195 the string MSG_MESSAGING_DFEAULTS (I assume it was supposed to be MSG_MESSAGING_DEFAULTS) contain double quote, but these double quote are escaped in the .po file. With this unescapped character, the javascript fail, and I can't use the save button for saving user. Work fine in english.
Hi Bastien, this needs to be fixed in the translation (on translate.koha-community.org) for the French translation. You should always avoid adding quotes or using different quotes to the ones in the text you translate - this can break JavaScript as is the case here. I don't speak French, so I have copied the translation from 19.05 that didn't use quotes for the other versions: Modifier les préférences de notifications par défaut pour cette catégorie d'adhérent ? I hope this fixes your issue.
