Hello - using latest version of Joomla and have just upgraded CMC Mailchimp for Joomla to v3. I've created a new API key and inserted that in component options. Module still looks good. Trouble is when testing - I insert a user who isn't subscribed to any of my lists. Hit subscribe and absolutely nothing happens. On Edge it doesn't do a thing, chrome and firefox it looks like it's thinking about it but ultimately just hangs. No error messages. Nothing. User doesn't appear on Mailchimp lists in Joomla or Mailchimp. Can you please help me troubleshoot? You can view the site here --- http://collectorhotel.com.au Newsletter Signup form is at bottom of homepage.

Many thanks, Julie
