Display latest post in header

The setting would be in the header element:

Thanks, Leo!

I tried it but that also didn't do the trick...

But it doesn't show an error on my site now:

string(71) "https://www.kevin-indig.com/wp-content/uploads/2019/07/learning-seo.jpg"

It seems to try pulling the image in.

What if you remove the var_dump() line now?

No luck :/.

I'm still seeing the var_dump at the top of the site.

It's returning the proper URL, so it should be working. Which page is the Hero on again?
