I think I have a quick fix solution. Jesse please confirm.
Follow these steps:
- Where ever you have your Joomla files hosted navigate to modules->mod_mailchimp2
- Open mod_mailchimp2.php
- On line 114 delete/comment out the code "$api = new MCAPI($params->get('mc_username'),$params->get('mc_password'));"
- Add a new line of code "$api = new MCAPI('12b10abcd194583f8e76ab2bb52ef4f6-us1');"
- Please change the API Key in the quote marks to whatever your API Key is
- You can find your API Key by logging in to your Mailchimp account and navigating to Account->API Keys & Authorized Apps
- Save this file
- In the same folder as mod_mailchimp2.php open send_to_mc.php
- On line 73 delete/comment out the code "$api = new MCAPI($login_name,$password);"
- Add a new line of code "$api = new MCAPI('12b10abcd194583f8e76ab2bb52ef4f6-us1');"
- Please change the API Key in the quote marks to whatever your API Key is like previously
- Save this file
Now to test, navigate to your website where your MailChimp module gets loaded and refresh the page. Now log in to your MailChimp account and navigate to Account->API Keys & Authorized Apps. Scroll down the page to "Last 24 hours of API calls" and you should not be able to see the "login" item in the "Method" column for that recently refreshed page. This means you're no longer using the login() api method.
Hope this helps.
