Hi Chouby,
No the problem is that all my fields copy the text of the motherpage into the second language page. So not only the ones i filter in the functions.php. The results in the site are now also completely messed up. :( French Dutch and English is messing up in random way. very strange.
Here an example http://piscines-vacances-provence.com/house/mas-des-roses-nl/
Hope you can help.
Thanks!
