Misdirection of buttons on multilingual site

[ermedigital]

Hello;

1-) I am using a multilingual website. When I add a product to the cart, I try to go from the mini cart to the cart, but the page is not found or I get an error to redirect to the homepage.

2-) Filters are active on category pages and although there are variations in my products, the filters do not appear.

3-) I add products to the wish list and go to the wish list page, but instead of the add to cart button, there is a select option button and it redirects to the homepage.

my website url: www.saveurselects.eu
