this.elements.$settingsFormPage missing and getting error. this error making conflict with another plugin hash tags. We need a IF control like this.

var $activePages = this.elements.$settingsFormPages;

if ( ! $activePages.length ) {
  return;
}

var $activePage = $activePages.filter( '#' + tabName );
