I got this error when i tried to go to http://localhost:3002/admin/sites/1:

ActionView::TemplateError (Menu is not missing constant SectionsMenu!) on line #16 of vendor/plugins/adva_cms/app/views/layouts/admin.html.erb:

        end

This is when I use the tip commit from your master branch plus my Ruby 1.9 fixes (since I refuse to use ancient 1.8 and it didn't seem to make sense to ask you to pull from a fork of tag/0.3.0):

Anyone know a solution? Is this related to https://rails.lighthouseapp.com/projects/8994-ruby-on-rails/tickets/2283-unnecessary-exception-raised-in-asdependenciesload_missing_constant ?

By the way, it seems to be an issue when I use tag/0.3.0 too. I don't understand why...

I'm using Ruby 1.9.1 and am also stumped by this bug. Because of this bug, I'm going to have to give up on trying to use adva-cms, at least for now. I tested using the Rails 2.3.6 development branch with the 0002-backport-compute-type-fix.diff patch mentioned in https://rails.lighthouseapp.com/projects/8994-ruby-on-rails/tickets/2283-unnecessary-exception-raised-in-asdependenciesload_missing_constant with little success.
