Hi, I would like to translate the forum into Chinese, and I have set the Wordpress as Chinese version. I can see in the wpforo-zh_CN.po file, all the phrases have been translated, and I also translated the unchanged phrases in 'Forum - Phrases' and cleared the phrase cache. However, those phrases remained English in my forum, such as "Unread Posts", "Forum Icons" and so on. What should I do to make every word translated?

Thank you very much.
