Prestashop redirect problem after saving/editing a product

[Anonym]

I am using ps 1.3.6 on a shop and I want to know if it possible after editting and saving a product to redirect me on the same category where it was the product i edited , not to root category . 

 

I have another shop , the same version and there it redirects me on the same category where it was the product , not to the root category .

This is the AdminProducts.php file in the attachement .
