Sorry, maybe I’m not explaining well what the issue is. The problem occurs when I change the language of the WordPress website in Settings, General. No language plugins involved. Here I try to explain better:
I’ve got to build several different websites in different languages. The websites are identical (except for the language). When I clone one and change the language of the website (in settings -> general) everything works just fine, except for the event details. That 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 those. The theme is yours “?E?vent??L?ist?ing?”? and the only plugins installed are your 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 your help.
