Phlox Single Portfolio Remove Featured Image

Hey there,

I’m using Phlox portfolios on my website but now I have a problem: I want to show featured images on archive pages but not in single portfolio view. When I set „display:none“ to the class „entry-media“ the images disappear everywhere of course. Is there a way to remove it only from single page?

I already tried with a child-theme, adding its own class, but maybe I edit the wrong file? Which one is it? single-post.php or different one?

Please help!

Thank you!!
