Thank you for answering :) I got the slider-stuff to translate and the bottom welcome-footer.Which is amazing.
Although I am not sure I understand exactly how Polylang interacts with with wordpress. I cannot seem to translate the boxes.. Which seem to be grouped. I'm quite confused. Also there is the "read more" link on the slider that I also cant seem to figure out.
How do I find all this stuff out? I have tried re-reading the documentation for both polylang and WPML.
Thank you so much again though :) I will keep playing with the config file to see what I can find out. But help is appreciated.
