Thanks for the reply. However, I am using 2 separated pages for 2 different languages and link them together. So in Wordpress they are 2 physical pages and WPML just links them together. In the header builder it only shows Chinese version now.
So it doesn't involve any translation process. I am not sure if you understand my explanation. Could you mind to login to my website to take a look?
We need to launch the website soon and I really need to solve the problem.
