当我尝试在我的模块上保存更改时，它说权限被拒绝。我很确定它来自控制器文件。我已启用用户组的所有权限：“管理员”。但我真的不知道它来自哪里，因为这是我的第一个 Opencart 3 模块。我相信它与帖子部分有关，因为它仅在保存后才会出现。
控制器文件中的代码：
<?php
class Controllerextensionmodulecartreminder extends Controller {
private $error = array(); // This is used to set the errors, if any.
public function index() {
// Loading the language file of cart reminder
$this->load->language('extension/module/cartreminder');
// Set the title of the page to the heading title in the Language file i.e., Cart Reminder
$this->document->setTitle($this->language->get('heading_title'));
// Load the Setting Model (All of the OpenCart Module & General Settings are saved using this Model )
$this->load->model('setting/setting');
// Start If: Validates and check if data is coming by save (POST) method
if (($this->request->server['REQUEST_METHOD'] == 'POST') && $this->validate()) {
// Parse all the coming data to Setting Model to save it in database.
$this->model_setting_setting->editSetting('cartreminder', $this->request->post);
// To display the success text on data save
$this->session->data['success'] = $this->language->get('text_success');
