Wordpress plugin: Type E_Error

The other day I connected Patreon to my Wordpress site. At first it worked fine, the posts were synced and everything was fine.

After installing the plugin I’ve made two changes: I updated my Wordpress, and I tried to make the Patreon sync to Pages instead of Posts. Not sure if these might be related, but the error started occurring after the changes.

I can’t disconnect or reconnect the page. Deleting and re-installing the plugin doesn’t work.
I also tried deleting the API Client from Patreon itself, without any change.

This is what is in the error e-mail I received:

When seeking help with this issue, you may be asked for some of the following information:
