what determines the language step booking form is shown in?

i have it in dutch and english but as far as i can tell always dutch is shown

should it switch dependand on browser locale?
can the language be forced, for example by parameter, or by wordpress page options?

Hi Marko

thanks for that information

so i have backend in dutch, frontend amelia normally also showing in dutch
so i am adding a additional reservartion page that i want to show in english

slug = reservationenus
https://jinda-massage.nl/reservationenus/

so im trying to set that page locale to english

what i found online how to do it is like this

add_filter('locale', function($locale) {
    $path = trim($_SERVER['REQUEST_URI'], "/");

    // get last part as slug
    $arr = explode("/", $path);
    $slug = end($arr);

    if($slug === 'reservationenus') {
      return 'en_US';
}

    return $locale;
});

function yst_wpseo_change_og_locale( $locale ) {
    return 'en_us';
}
but it doesnt work, still seeying it in dutch

how can i set the frontend page local so that it shows in english?
and by the way what locale works for amelia for english is it "en" "en_US" "en_GB" or does any of these work?

Thanks very much for your help.

ok yeah i seen that too, ok i will manage to change it somehow, ill investigate

thanks
