Release 2.3.0

After updating to 2.3.0, I’m getting a 403 (Forbidden, Access to this resource on the server is denied!) error when attempting to save changes I made to a contributor. I wanted to add a YouTube channel.
I had the same problem once before. Updating to a newer version of Podlove did help the last time. Obviously, this is not possible this time, since there is no newer version yet.

I can add a new contributor though. But I can’t add social services.

The repair option within the Podlove plugin did not help.

It seems like I can edit everything except the social services: More specificly: I only get the error, if the Account/URL box is used.
