I have the following error A new version of Event Espresso – MailChimp (EE4.4.5+) is available. View What’s New with version 2.4.4.p. A valid Support License Key is needed to enable automatic upgrades. Your current account does not allow automatic upgrades on more than one domain. Please log in to your Event Espresso account to manage your Support License Keys or purchase a support license right now. As far as I’m aware I only have one domain
I’ve reset your support license key. You can click the dismiss button on that notice, then go to your site’s Event Espresso > General Settings page, and click the save button. At that point does the error message display again or does the plugins page allow you to update the MailChimp add-on?
