Hi Christopher
I am seeing your images showing at 90×60. This is likely your media setting at “Medium” under Settings » Media.
However, the CSS from our plugin and your theme indicate you can make the images 300px wide.
Can you test the following code to your child theme, or in Appearance » Customize » Additional CSS?
.tribe-events-event-image {width: 90% !important}
You can see the images displaying in list view now, but the one event with a thinner image moves the text left as well. This is not typical behavior with other themes, but your theme seems to need a little help styling this area.
Let me know if this solution works.
Thanks
Courtney 🙂
