Here’s a link to instructions on how to display your directory:
The short version is to add [
connections] to the page you wish to embed the directory and publish it. Ensure the publish page is set as the Directory Homepage on the Connections Settings admin page under the General tab.
To use the Slim Plus template to display the directory, install the zip file as a new Plugin, activate the plugin, navigate to the Connections Templates admin page, and click the Activate button for Slim Plus.
I hope this helps!
