I have been following the instructions for integrating Mailchimp: https://wiki.foxycart.com/integration/mailchimp
And manage to proceed to the testing part using test.xmldatafeed.php
When opening this file in my browser I received the following errorUnable to load listSubscribe()! MailChimp reported error: Code=502 Msg=Something went wrong, please try again later.
I have double checked the datafeed keys and URL files for both Foxycart Store > Advanced and fc-mailchimp.php
What other issues could it be? The step before this was successful (https://wiki.foxycart.com/integration/mailchimp_test
) and I manage to add an entry into my Mailchimp list. Any advice will be great.
