Why the advocacy (action) registration or supporter information form is giving blank form?

admin/structure/block/manage/salsa_advocacy/*/configure

Which block is showing nothing.
Is this block supposed show the user information to submit the corresponding action ?

I think this code under salsa_advocacy.module

function salsa_advocacy_block_view($delta = '') {
  $block = array();
  $action_page = entity_load_single('salsa_action', $delta);

  $block['subject'] = is_object($action_page) ? $action_page->Reference_Name : t('Error loading page');
  $block['content'] = is_object($action_page) ? $action_page->buildContent() : t('Content is currently not available. Please click !reload_link to refresh the page.', array('!reload_link' => l(t('here'), current_path())));

  return $block;
}

returning nothing.
