Anyone worked with Sitealizer? Having a problem with it

here is the error message.

NoMethodError in Sitealizer#menu

Showing vendor/plugins/sitealizer/lib/app/views/sitealizer/menu.rhtml
where line #7 raised:

undefined method `name' for "<option selected value=04>04</

Extracted source (around line #7):

m> [m.name, m.number]}) %>
8: <%= select_tag :year, options_for_select(@years.collect {|y|

Thanx,
