DDoS protection by cloudflare open cart appeared in modules?

Question

opencart

I didn’t connect any protections, the hoster didn’t do anything either, but the following appeared in the admin panel in the modules.

I can’t understand what it is and where it comes from. The page reloads after 5 seconds.

Do not worry, these are problems on the server from which the ads are being pulled. You can treat it like this:
In the fileadmin/controller/extension/extension/promotion.php

class ControllerExtensionExtensionPromotion extends Controller {
  public function index() {

        return '';
//		$curl = curl_init();
//
//		curl_setopt($curl, CURLOPT_URL, OPENCART_SERVER . 'index.php?route=api/promotion&type=' . substr($this->request->get['route'], strrpos($this->request->get['route'], '/') + 1));
//		curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
//		curl_setopt($curl, CURLOPT_HEADER, false);
//		curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);
//		curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 30);
//		curl_setopt($curl, CURLOPT_TIMEOUT, 30);
//
//		$response = curl_exec($curl);
//
//		curl_close($curl);
//
//		if ($response) {
//			return $response;
//		} else {
//			return '';
//		}
  }
}

Comment out the controller code (or delete it) and return the empty line. This will get rid of ads forever.
