I type in wrong root domain url such as 3dlens .com/xxx It redirect to 404 page not found.
However when I type in any wrong subfolder url for example: 3dlens .com/japan/xxx It did Not redirect to 404 page. It appers “there is no this item in your cart”
How to redirect wrong subfolder url to 404 page?
Note: Japan folder store use different database with SEO url.
If you go here http://tools.seobook.com/server-header-checker/ you'll see that second URL does return a 404 response but I don't see how you can forward that to 404.php - maybe somebody else knows a way but that in theory is a possible product detail page (if xxx was the product name)
