Komento not working after migrating to J3

Hello,
I just migrated to J3 and althoug the comments are still in the database, they're not being displayed in the frontend.

I see the error: Notice: Undefined property: stdClass::$catid in /components/com_komento/komento_plugins/abstract.php on line 353

Also, in the backend the administration area looks a bit disorganised.

Can you support with this?

Thank you
