Prestashop : Declaration of AdminLoginControllerCore::viewAccess() must be compatible with AdminControllerCore:

Question

I was using prestashop on hosting with no problem. Now I started my home web server and I'm trying to get it working.

I tried many different prestashop versions and reinstalled them x times.. All the time problem is that, I can Access front panel, but not the backend panel..

All the time it shows Http 500 ERROR : Server can't Handle this request. Now I enabled debugging and it shows me error:

Fatal error: Declaration of AdminLoginControllerCore::viewAccess() must be compatible with AdminControllerCore::viewAccess($disable = false) in C:\xampp\htdocs\Shop\controllers\admin\AdminLoginController.php on line 27

And Line

class AdminLoginControllerCore extends AdminController{

I can't understand why this is happening, becouse I haven't edited and changed any file or folder.

Answer 1

It happens because you have to implement a method in a child class with all parameters of a parent class method. So in your parent class viewAccess has a parameter $disable=false and you need to have it in your child viewAccess() declaration. Just put that parameter in the declaration public function viewAccess($disable=false) and you even need not use it inside. And why it was not showing on the hosting but show in a local machine it is sooner in due to different PHP versions on the servers. Because in different versions it has different error levels.

Answer 2

The way to fix this is simple:

go to ROOT/controllers\admin\AdminLoginController.php al line 153 you’ll have to change public function viewAccess() to public function viewAccess($disable = false).
