<?php

use mQueue\Model\UserMapper;

class CssController extends Zend_Controller_Action
{
    public function init(): void
    {
        $this->_helper->layout->disableLayout();

The method disableLayout() does not exist on Zend_Controller_Action_Helper_Abstract. It seems like you code against a sub-type of Zend_Controller_Action_Helper_Abstract such as Zend_Controller_Action_Helper_Cache or Zend_Controller_Action_Helper_Redirector or Zend_Layout_Controller_Action_Helper_Layout.

        $this->_helper->headers('text/css');
    }

    public function gravatarCssAction(): void
    {
        $this->view->users = UserMapper::fetchAll();
    }
}
