Ajax error post when click on variant dropdown in product page

[Andriano]

I have this error :

POST https://website/fr/index.php?controller=product&token=ddbe02f07d79f8c94a34355b3bd34c8a&id_product=19&id_customization=0&group[4]=27&qty=1 [HTTP/2 404 Not Found 302ms]

when i click on variant dropdown or quick view(POST https://website/fr/index.php?controller=product 404).

We can buy variants products, its just when i click on variant dropdown on product page, the url not change and price.

Any Ideas ?

Hello, Which PrestaShop you are using. What is your php version . Is this custom theme or PrestaShop default theme.

 

Thank you
