ERR_BLOCKED_BY_XSS_AUDITOR

I think this happen after my hosting provider update php version but not sure. Where to find problem , thanks ?

This is a Chrome bug, not an openCart issue. Try using different browser, or this: edit file admin/controller/startup/startup.php and add this line anywhere inside function index:

Problem is same in IE and other browser - when I click on SAVE opencart logout automaticaly and show message "cannot find page"

I wass try add funkction and code looks like this:
<?php
class ControllerStartupStartup extends Controller {
public function index() { $this->response->addHeader('X-XSS-Protection:0');
// Settings
$query = $this->db->query("SELECT * FROM " . DB_PREFIX . "setting WHERE store_id = '0'");

but problem is still there. did I paste funkction on right place ? There is only one public function index() in this file.
