Images not displaying on frontend of website

I went to my website and published a post today and realized that all of a sudden none of the images are displaying on the front-end of my side. This problem seems to only occur on the Single Post page. As you can see, only the alt text is showing.

The WordPress gallery works fine in the WordPress admin section. I’m able to upload and add pics to a post no problem. But on the front end, nothing shows up.

I tried using the Regenerate Thumbnails plugin also but had no success.
