Edit Selected 404

Hi,

When I try to edit multi products same way as the documentation:

https://docs.cs-cart.com/latest/user_guide/manage_products/products/same_value_all_products.html

I have 404 Page Not Found and the link return this:

https://mysite.com/admin.php?dispatch=products.update&product_id=0&selected_section=detailed&page=1

I got nothing on the log files.

cs-cart 4.13.2.SP2 MULTIVENDOR

Any idea?

thanks

				4.13.2.SP2
