Featured image orientation - images are not scaled properly

Hi, Can someone explain me how to set up featured image to set like landscape like in attacment (2) not like (1)

I guess some plugin is overwriting default theme settings, so you need to apply styling again.

Add this Custom CSS to Appearance >> Theme Options >> Other >> Custom CSS.

.thumbnail {
  height: auto;

Let me know if this works for you.

That’s it, thanks a lot!
