Locales are in the right place, and they have the right permissions and the right translation, but OJS don’t show es_ES navigation menu strings (ie: navigation.about).
If I visit the new translation tool, looks like in the database the translation is “navigation.about” instead of the “Acerca de”.

So first questions is: In OJS 3.1, is there a way to force a locale reload?
Translation was fine in OJS 3.0.2 so, looks like the problem could be related with navigation.menus being now a plugin with a new locale file, isn’t it? I will check it tomorrow.
