I've searched thoroughly and seen this issue covered in several ways that didn't seem to apply to my configuration. So thanks in advance for any time and help.
Here's my site: http://www.playrockreggae.com/
The Home page (which is showing latest posts) shows each post's Featured Image(post thumbnail) plus the post excerpt. I'd like to know how and where to change the PHP to make the other main menu items (Video Premiere, Music Premiere, etc -- which are all Categories) show just like the Home page. As of now, only the Home page shows the Featured Images alongside the post excerpt, while all other pages only display the post title and excerpt.
My theme is Pagelines WhiteHouse Pro v3.0.1 using WP v3.4.2. Other solutions refer to a loop.php file, which doesn't seem to exist in my theme. Seems easy enough but I'm just not familiar with PHP.
