I’m sorry my explanation isn’t specific.^^;
My issue :
Currently I use 3 languages in wpml.
1. I set up a ‘chat page’ in English.
2. I switched to Chinese and set ‘chat page’
3. When I switch back to English, my chat page is ‘disable’ (dropdown selection)
When there are two or more wpml languages, I can only set chat pages in one language. All other languages are disabled.
