Question

Fatal error: Call to undefined method
Desbest_Brands_Adminhtml_BrandsController::_addBreadcrumb() in
/home/desbest/public_html/clients/magentofull/app/code/local/Desbest/Brands/controllers/Adminhtml/BrandsController.php
on line 8

Fatal error: Call to undefined method
Desbest_Brands_Adminhtml_BrandsController::_setActiveMenu() in
/home/desbest/public_html/clients/magentofull/app/code/local/Desbest/Brands/controllers/Adminhtml/BrandsController.php
on line 7

From what I see, the Data.php file inside Helpers/ folder should be left as it is blank like what the tutorials say.

So what’s with the errors?

Answer 1

Seems you controller class is extended from Mage_Core_Controller_Front_Action. You should extend it from Mage_Adminhtml_Controller_Action class instead, because only it has methods called _addBreadcrumb() and _setActiveMenu().
