[ERROR] admin_general#index (I18n::InvalidLocale) ":en is not a valid locale"

[lizconlan]

This is the same error message we saw on the Belgium site. In that case it turned out to be a Rails 4.0 date handling bug https://github.com/mysociety/belgium-theme/issues/57 (it assumes English will always be available and raises an error when it isn't)

If this is what's happening here, hotfix/0.28.0.12 should fix it (current site version is 0.28.0.5)

An I18n::InvalidLocale occurred in admin_general#index:

  :en is not a valid locale

Error on screen is

<a class="accordion-toggle" href="#unclassified" data-toggle="collapse" data-parent="things-to-do"><span class="label label-important"><%=@old_unclassified.size%></span><%= chevron_right %> Classify responses that are still unclassified <%=InfoRequest::OLD_AGE_IN_DAYS.inspect %> after response</a>

so it is the Rails 4.0 bug

(the error just now was me recreating it)

will be fixed by #38

This page now loads, so closing this as fixed.
