I found this too at first install of the plugin.
1. Make sure you have MySQL on your server installed and create a new SAM user with read-access to your SAM database. Don’t use “root”, otherwise you’ll get an error message saying you have to create another user.
2. In your WordPress “Settings” select the NGS SAM Integrator plugin settings and ensure your database configuration is properly defined.
3. Add widgets to your page. They are “Recently played”, “Coming Up”, “Requests” which contains your playlist and “Top Requests” which is a list of those songs which your viewers have requested.
4. Ensure the first page of your WordPress page is one of the pages that was automatically generated when you installed the plugin.
These few tips should get you going. Let me know if you have any other problems. I’ll see what I can do to help.
