A common error that could appear after you install prestashop is
Fatal error: Declaration of AdminLoginControllerCore::viewAccess() must be compatible with AdminControllerCore::viewAccess($disable = false) in /var/www/prestashop/controllers/admin/AdminLoginController.php on line 27
or, if you haven’t set prestashop into dev mode, you’ll get a 500 error.
The way to fix this is simple:
- go to ROOT/controllers\admin\AdminLoginController.php
- al line 153 you’ll have to change
public function viewAccess() to public function viewAccess($disable = false)
After you did this, your admin should appear.

It works! Thank you so much! Why this happened???

honestly, at the moment i have not idea, because the ControllerCore abstract class has the method without parameters, BUT the AdminControllerCore class, that extends ControllerCore , had it with that parameter… so basically someone forgot something… also i used prestashop 1.6.1.18, Also if you search the AdminController class that was extended by AdminLoginControllerCore, you;ll see it was registered but without a path, but pretashop “knows” how to fix the exntension of the class so that it won;t say “Oooops”. So sorry i couldn;t give you a good answer.
