Testing the updates on the site, I found that the annotation menus weren't appearing for three files:
bon_menage.xmlcoquette.xmlinvention_des_femmes_1.xml
On further investigation, I discovered that these files had empty annotations (annotations which contained nothing at all, or which had only titles and no content). I fixed this by deleting those which had nothing at all in them, and adding a non-breaking space to those which had a title but no content.
