Hello Matt,
Welcome to the forums 🙂
I took a look at the link provided and noticed some missing images as described. Are you using a shortcode to call the events onto your home page?
Additionally, does the issue occur when reverting back to the default WP theme as outlined in our Testing for conflicts guide? Theme customizations/support unfortunately extend beyond the scope of support we’re able to provide through the forums, so please be aware of that.
One more bit of information I can provide would be to look over our tribe_event_featured_image documentation. You should be able to pull in the image with this information.
I hope this helps and have a good week. Thanks for choosing PRO!
