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?
