I was using an RSS feed of latest.rss pushed into MailChimp to send an email 3 times a week to subscribers… But MailChimp is now saying the RSS Feed Link isn’t valid. Anyone else having trouble?
I am appending the ?api=xxxx key on the end of my URL since my forum is restricted to only logged in users. When I load the RSS feed URL in my browser, it loads up fine. But I tried both MailChimp and Mailerlite to see if I could get the RSS to email setup and both of them say the RSS feed is invalid.
