Cannot Update Side in Trunk

I am getting a spinning wheel when trying to update the sidebar. This
error is in my log file.

ActionController::MissingTemplate (Missing template
./script/…/config/…/app/views/admin/sidebar/set_active.rhtml):
/vendor/rails/actionpack/lib/action_controller/base.rb:935:in
assert_existance_of_template_file' /vendor/rails/actionpack/lib/action_controller/base.rb:654:inrender_file’
/vendor/rails/actionpack/lib/action_controller/base.rb:595:in
render_with_no_layout' /vendor/rails/actionpack/lib/action_controller/layout.rb:220:inrender_without_benchmark’

Thanks,
Chris
