Jammit не может упаковать tinyMCE

Когда я загружаю страницу с помощью tinyMCE, я получаю следующие ошибки:

«NetworkError: 404 Not Found — http://localhost:3000/users//langs/en.js" en.js "NetworkError: 404 Not Found - http://localhost:3000/users//themes/advanced/editor_template.js"

Путь кажется неправильным, но я понятия не имею, как это отлаживать.

Изменить: по запросу я добавляю код

приложение.js

tinyMCE.init({
          content_css : '/stylesheets/tinyMCE.css?bogus=1306384393',
          editor_selector : 'mceEditor',
          font_size_style_values : '10px,12px,13px,14px,16px,18px,20px',
          language : 'en',
          mode : 'textareas',
          theme : 'advanced',
          theme_advanced_buttons1 : 'bold,italic,underline,fontsizeselect,forecolor,|,bullist,numlist,|,outdent,indent, justifycenter,justifyright,justifyleft, blockquote',
          theme_advanced_buttons2 : '',
          theme_advanced_buttons3 : '',
          theme_advanced_containers_default_align : 'left',
          theme_advanced_font_sizes : '10px,12px,13px,14px,16px,18px,20px',
          theme_advanced_resizing : false,
          theme_advanced_toolbar_align : 'left',
          theme_advanced_toolbar_location : 'top'
          });
