Hello,
The Danish files are not translated. We didn’t want to use Google Translate. They can be found in booking-system/translations/frontend/dk.php & booking-system/translations/backend/dk.php. Open them with any editor and change the English text.
To change in Back End use top-right Drop Down.
For Front End use the shortcode [dopbs lang=dk].
The Booking Forms can be translated in Admin Booking Forms area.
Thank you
