The problem occurs when I change the language of the WordPress website in Settings, General. No language plugins involved. Please just don’t say “you need to ask the language plugin developers” and mark it resolved, is not resolved.
I’ve got to build several identical websites in different languages. The websites are identical (except for the language). When I clone one and change the language of the website (in wordpress -> settings -> general) everything works just fine, except for the event details. This page won’t show and I receive a 404 error.
This websites with the issue are dependencies of the main website and I don’t use any language plugins on them. The theme is “Event Listing” from the WP Event Manager Developers and the only plugins installed are WP Event Manager add ons.
I built a first website in italian and it works fine (no 404 issue). I then cloned it and changed the language in English and I got the issue. Thanks for reading.
