Exception #1513232660: For hash "" no API key found

[JavierYD]

I've just updated Typo3 to 8.7.9 and Mailchimp to version 3.0. An exception is triggered when I try to open any page that contains the plugin in the backend. Frontend output is OK and subscriptions are being done correctly.

This is the full exception report:

It does not fail if I open the plugin block through LIST instead of PAGE. Once there I've detected that all the plugin's settings are now lost. After configuring the plugin again the error is gone, so I guess that there was a problem with the update process.

[lochmueller]

Perhaps "Used API" and "List" should be "required fields" in the plugin configuration to avoid misconfiguration and errors in the page view?

Same problem is my instances...
