OK, I followed your steps above.
I'm getting an error message.
I can view the page with the PlayBuzz shortcode [playbuzz-hub] no problem. It displays PlayBuzz content properly. But, when that page is selected from the recommend widget, it produces an error when viewed in browser.
"Error.
Oh No!
We're Sorry, An Error Has Occurred.
Please try again later."
Also, using this widget, it changes our site favicon to the PlayBuzz favicon. As you might suspect, that's not acceptable.
Let me know how to proceed, please.
