The language switcher in barber/beauty headers reads $currentPageUrlArray[2] unguarded after exploding REQUEST_URI on '/'. On routes with no language prefix (e.g. POST /manage-booking-cancel rendering the cancelled page inline), the array has only 2 elements, triggering "Undefined array key 2" warnings and producing malformed language links like https://studiobeve.no/en//. Normalize the array with += [2 => '', 3 => ''] right after the explode so indices 2 and 3 always exist.
The file is empty.
