Trying to set this up on MCrider.com ***Errors***

Here is my test page:

Here is the error my Patrons are getting:
{
“error”: “invalid_request”,
“error_description”: “Mismatching redirect URI.”,
“state”: “YToyOntzOjE4OiJmaW5hbF9yZWRpcmVjdF91cmkiO3M6MzU6Imh0dHA6Ly93d3cubWNyaWRlci5jb20vcGF0cm9uLXRlc3QvIjtzOjEzOiJwYXRyZW9uX25vbmNlIjtzOjMyOiJkMzcyZTY4NDBiNTEzMDUwMTI0MGFkYjRiYzdkMDFkMCI7fQ==”
}

Any ideas on what the problem is?

The redirect uri setting in your plugin settings for Patreon WordPress does not match the one you saved into the client details at Patreon.

If those do not match, it will cause an error. A ‘/’ at the end of the url is also taken into account.
