HTTP 500 - Access level to ManufacturerController::$label must be protected

[fouratig]

Hello!

I've discovered that I can't access the manufacturers or suppliers page on my website (front end). I turned on debug mode and got this message:
 

Fatal error: Access level to ManufacturerController::$label must be protected (as in class ManufacturerControllerCore) or weaker in /home/*server*/*store-name*/override/controllers/front/listing/ManufacturerController.php on line 0

(Server and store name blurred out)

However, when I got in to ManufacturerController.php I can see that $label is declared as protected and I don't know how to go further with this. Any help is really appreciated!
EDIT: This is for all Brands, Manufacturer and Suppliers page. But only those.

Kind regards,

Elias

Change it to protected in  (Note the path)
/home/*server*/*store-name*/controllers/front/listing/ManufacturerController.php

OR 

Change it to private in 
/home/*server*/*store-name*/override/controllers/front/listing/ManufacturerController.php

In both the files, Access level must be the same. Some module has overridden the ManufacturerController & made the $label as protected while in the core file, Its private

Hello!

Thank you very much! I changed both to protected and now it works flawlessly!
