Hi Tim,
Thank you for your help!
I first installed the free version but immediately thought better of it and knew I wanted the pro version. Before I deleted it, I saw that it put the controls for it in the WordPress left side navbar. I deleted it and installed the pro version. It did not put anything on the left side but instead the only control I see is in the plug-in page where the options are Settings – Deactivate – Edit. I click Settings and I get an all white page with the error message. I only get this message when I click the Settings link on the plug-in.
Though not very helpful, I took a couple of screenshots and they’re here: https://gearupsports.net/files/FacebookFeed.jpg
I really appreciate your help.
