Property Hive plugin search search results

Hi,

I'm trying to use the Property Hive plugin with a child theme. My first problem was that the search form wasn't displayed but I found a solution in the forum. Now the form is displayed but the results aren't.

Normally the plugin adds a shortcode to the page. It didn't. I've adding the short code to the page but it makes no difference.

I'm using GeneratePress 2.0.2 with a child theme.

What am I missing?

Thanks,

Sam
