Can’t post in different languages

I’m unable to put anything in different languages on new posts now. I click on the different language tabs, but it just puts in the same info for everything. Then shows that no language has been selected when I post it. I’ve even tried putting it into raw mode, but even there, there are no other languages. I’m seeing old posts have different languages, but the newer stuff, no. 🙁 What has happened? I’ve updated wordpress. As is, there is no reason to keep this plugin just for old posts if I can’t have real multi-language on new things. HELP?
