Just putting it here to not forget, there is something wrong in the MARC21slim2intranetDetail.xsl for fr-FR I bet on a translation issue. ==> /var/log/koha/kohadev/plack-error.log <== Error while loading stylesheet xml: /home/vagrant/kohaclone/koha-tmpl/intranet-tmpl/prog/fr-FR/xslt/MARC21slim2intranetDetail.xsl:923: parser error : EntityRef: expecting ';' <span class="label">Note d'action : </span>
I can no longer locate the string "Note d'action" in any of the .xsl files. Closing fixed.
