Multilingual website offers only one language registration page

I use CB with multiple languages on my website.
However, when someone wants to register, the visitor is always redirected to the dutch page.

How can I make it word that the visitor comes to the right webpage with their own language to register?

Kind regards for any help

CB doesn't handle language switching. That's entirely on Joomla as CB just loads whatever language Joomla says is being used. You'll need a Joomla menu item for each language. So you'd need a menu item to CBs registration page for each language you intend to provide. As for Joomla language switching that's typically done with the language switcher module and the respective language system plugins.
