Is this plugin now defunct? No updates?

I have installed the plugin and filled out all required fields but it doesn’t seem to be working. It doesn’t like my development URL (deluxecamp.mgrenier.ca), I changed the URL to https://www.mgrenier.ca and it passes validation as in I don’t get the error, but it still doesn’t get setup properly. I assume it has something to do with the actual URL not matching the URL listed, but I get no errors it just doesn’t setup properly.

Any suggestions?
