I found a small issue with the Directory child theme. If you look at your demo and it’s the same on my install, the “Added By User” line is missing on the single listing display. It shows on the event listings but not on the place listings. You can see your demo does the same thing. The demo of the Vantage theme shows it fine.
Maybe you can send me the code to put where so it shows that info.
