Problem with url on prestashop, what to do?

Question

Apache HTTP Server

Hello!
prestashop 1.6.1.6
I ask for help with this issue:
there is a manufacturer page of this type:
site.com/designers/pasha
if I remove the letter and write like this:
site.com/designer/pasha
throws me to the page:
error
products are missing
if I remove or I add letters to the name of the manufacturer, for example:
site.com/designers/pashasdfsfsfsd
a page with all manufacturers is displayed, but the address remains like this:
site.com/designers/pashasdfsfsfsd
If I understand correctly, any change in the url should redirect me to 404, but it only redirects me to category or product pages, and it’s such a problem with manufacturers.
Another moment there is a payment module through Yandex, with the CNC turned off, it works as it should, with the CNC turned on, when paying, it transfers to 404,
what should I do? help me please

Answer 1

This happens because Presta converts your url from /designers/pashasdfsfsfsd to ?designers=pashasdfsdsdsf,
this is such an alternative way to work with filters
