Hi Vasch,

Have you tried to change permalinks to default, Plain?

Hi Benjamin,
I commented on an existing topic with the same issues: https://www.ads-software.com/support/topic/url-404-result-not-working-with-polylang-and-permalink-set-to-post-name/

Yes, setting the permalinks to default solves it. However, due to the amount of internal and external links to lots of pages on the site, it is not possible to use other permalinks than page name.
