I guess this is fixed by 8a6c606 but I wanted to

a) check before I add 1 patch to the version we're running
b) query the name of mysql4-upgrade-1.1.19-1.1.20.php in the commit, in case that messes up upgrading to 1.1.21 later

Thanks for your feedback @rbrown

In the meantime you can just replace:
$this->getHelper();
With
Mage::helper('mailchimp');

Kind Regards.

Yes, I started the cron up again and it's happy, thank you

Hello @rbrown.

This issue will get solved with our next release (v1.1.21). As you can see here, the method name had been changed to 'getMailchimpHelper' and this issue doesn't happen anymore.

Thanks for your feedback.

Regards,
Javier Giorello.
