If there are templates and partials in a database they have to be written to a disk into /tmp/views directory. It is being written when you create or update them but after deployment the directory is cleared and no views are written.
It is happening only in rails 3 versions of browsercms.
There is this file: /browsercms-3.3.3/lib/cms/init.rb
And line "DynamicView.write_all_to_disk! if DynamicView.table_exists?" is commented out in rails 3.
