404 shows on frontpages

Hi

I have a problem after implementing Polylang on our company website.

I have choosen a static frontpage under Setitngs, and tried to flush permalinks, but with no success. When I try to navigate to a specific language eg. https://www.adservice.com/no/, it won’t redirect me to the norwegian frontpage at https://www.adservice.com/no/no – it just shows me a 404.

Do I need to make some changes to our .htaccess file or is it some settings I haven’t set correctly.

If you google “adservice”, then we have some sitelinks with the different languages, but they lead to eg. https://www.adservice.com/no/ and a 404-page.
