Thumbnails not showing up

I’ve been fighting with this Genesis Grid Loop plugin for weeks now and no matter how I try, I can’t get the images to show up. I’ve seen it work great for other sites, so I’m hoping I can get a little help here.

I was able to remove the byline details and all the other extraneous information I didn’t want to show up in the archives, but the photos disappeared too. The directive that removes the byline, etc, also takes out the photos.

Here’s the staging server, with the plugin installed:

https://staging.bendejes.us/category/savory/

You’ll see the grid looks good, as do the titles. But the thumbnails just aren’t cooperating. I’ve regenerated them and gone through and made sure the first six or so posts in the savory category have featured images set, and still no dice. Sigh.

Any ideas on what might be the problem?

Here’s the css I’m using:

/* Genesis Grid Loop Styling ----------- */

.archive .teaser {
height: 150px;
}

.teaser .entry-content,
.teaser .post-info,
.teaser .post-meta {
display: none;
visibility: hidden;
}

.archive .post,
.search .post,
.tag .post {
margin-bottom: 20px;
}

.archive .teaser h2,
.archive .teaser h2 a {
font-size: 16px;
height: 62px;
text-align: center;
}

.teaser .post-image {
display: inline;
margin: 0 24px 5px 0;
}
