Hi Deni,
Thanks for your reply.
I have set my default joomla language to be chinese.
In extensions -> Language manager -> Chinese
but when i visited the page, and click into User Profile it is still displaying in English.
Anything else i am missing? do i need to set anything in the CB configuration ?
I tried several ways to enable chinese fields for CB, including Joomfish + CB content elements, but in Joomfish when i clicked the content element files, it simply display blank page.
