I cannot connect the Patreon WordPress Plugin with Patreon.
The Setup wizard doesn’t work (when I click “Allow” to “Create an OAuth client for your campaign”, I receive the error " Fatal error : Uncaught Error: Call to undefined method Patreon_API::create_refresh_client()").
I tried to connect manually (I created a Client, copied the Redirect URI from the Plugin, chose v2, and then copied the 4 credentials back to the plugin). The system says Success, but I cannot see the tires on the post editor.
I deleted and reinstalled the Patreon plugin many times, but nothing changed.
I noticed two odd things:
1. When I delete and reinstall the plugin the settings are remembered including the custom call to action! Perhaps, the plugin also “remembers” some old settings?!
2. When I run the Setup wizard, the client is automatically deleted form the Patreon’s page (and I have to create it again).
Any suggestion what I might do?
