I love that you can have multiple instances of the widget apply to different lists, so I'm really excited to use the plugin, but I'm having a couple challenges.
First, is that sometimes I get this message at the top of the widget box, which I think might be causing some of the other challenges:
Warning: Invalid argument supplied for foreach() in /mailchimp-widget/lib/ns_widget_mailchimp.class.php on line 90
Next, I can't get confirmation message, when an email address is successfully entered, to show up.
Thanks so much!
