A new 1.9.13 version was just released, it should fix a few bugs, including the error showing incorrectly.
@Tomasz just confirmed with me that the error message is gone after updating their plugin.
For folks experiencing the issue:
- Please update your WP Patreon plugin to the latest
1.9.13version - [optional] - step through the re-connect flow to reset your connection credentials
@Fable_Weaver can you please confirm that the issue is fixed for you too after the above steps?
Thanks everyone for reporting this.
