Problem with Classifieds - content not showing

Hi there, I have problem with classifieds plugin. I can't add any content to ad (text or media) just nothing appearing in the box. I can't type text there or insert image. Nothing. But I can add all other details. When ad is published I can see images that I try to add, but not any text. And there is no any featured image on page with listing all ads. Can you please help me regards this issue? Thanks
