  missing closing } maybe ? check syntax coz that is what it looks like .

  I would use this to load css files

  public function base_render_before ($sender) {
   $Sender->AddCssFile('widgets.css', 'plugins/Widgets');
      }

  public function base_render_before ($sender) {
      $Sender->AddCssFile('widgets.css', 'plugins/Widgets');
  
      $controllers = [
          // ControllerName => Modules for Name Controllers.
          'categoriescontroller'  => ['Twitter','Exchange'],
          'discussioncontroller'  => ['Twitter'],
          'discussionscontroller' => ['Dolartoday', 'Twitter']

  That would not cause an issue as far as I know....

  $Sender is the same thing as $sender . It's a mater of style not function. Vanilla code now requires or at least suggests that it should be $sender . But it should not affect the php function as far as the meaning ...

  It actually does, since variables in PHP are case sensitive (only methods are case insensitive):

  This line defined an argument $sender

  @terabytefrelance said:
  public function assetModel_styleCss_handler ($sender) {

  And this line references a variable $Sender which !== $sender.

          $Sender->AddCssFile('widgets.css', 'plugins/Widgets');
  

  As long as you stay consistent you can use either $Sender or $sender as you said, but if you mix them bad things happen (as terabytefrelance figured out).
