Problem with CKEditor for WordPress

I got some problem when “CKEditor for WordPress” is active.

Look, there’s no button or visual editor, it’s just a simple textarea.

Tried to upload an image and it’s done successfully, but no image in the editor (textarea in this case) 🙁

After posting, still no image on that question. Also there’s no buttons in answer section.

Everything works fine when I disable “CKEditor for WordPress” plugin. Is there any solution for this problem?

Thanks in advance.
