Hi Tom.
Please excuse the (extreme) tardiness of my reply.
I had added this code via the method you recommended: https://imgur.com/369d2wX + https://imgur.com/LIymqKA
I presumed that was all I needed to do. But reading the guide again, I realized that this was just to *show* the plugin updates. When I check my plugin dashboard though, the version is still on 0.5: https://imgur.com/DuK1tUO
Am I doing something wrong? If this doesn’t work I can always try the manual upload method – but I wanted to try this method first, since I was (am) hesitant to delete WPSP and reupload.
Thank you very much for your support Tom.
