Oauth for Word Press Error

[JohnCourt]

Good day folks, I have set up my Oauth for Word Press, using "Option B" at this tutorial https://invisioncommunity.com/4guides/how-to-use-ips-community-suite/social-sign-in/43-and-above/wordpress-r304/

I have followed the instructions verbatim, when I go to test the configuration at the miniOrange oauth plugin on my Word Press site, I get this error message:

I went ahead and installed the login button per instructions, for the Word Press site, and I am still getting the same error message, has anyone had any experience with this?

Thanks for any help.

John
