How can I install Patreon Wordpress Plugin FRESH?

I have used (checked out) the wordpress plugin in the past year.
When I tried to install it again, the settings from the past installations, including the fully customized call to action page and client ID, Secret, tokens are still there.

How can I install the plugin fresh, so to be able to connect to Patreon?

I don’t use any caching plugin. I have used some in the past, but I tried to delete all possible cache.

You would need to delete all the existing details for connection - Connection button should show them.

Then you can use ‘Connect’ button to connect your site.
